Obsidian repeatedly crashes when sent to the background on iPhone 17 Pro

Once you’ve done the above, delete everything above this line.

Sigrunixia asked me to log this, following on from the discussion starting here: Discord

I have held off reporting it since the only reproduction I know involves uploading my whole personal vault, which of course isn’t going to happen.

So I’ll start by logging the info that Sig requested, and add some more stuff that I can think of. And maybe we can grow the info from there…

Steps to reproduce

The normal step:

  1. On my iPhone 17 Pro, load Obsidian, and interact read or edit a note
  2. Swipe up from the bottom of the screen, to send Obsidian to the background
  3. Open another app
  4. Many times a day, within 10 to 30 seconds there will be a message from the OS saying that Obsidian has crashed, and do I want to report the issue to the developer (I run the latest TestFlight versions)

Did you follow the troubleshooting guide? [Y/N]

Please, follow the Troubleshooting Guide before answering Yes.

Yes. Back on 11th July, I disabled all themes, plugins and snippets, and ran Obsidian for some time, and still sometimes got crashes from Obsidian in the background.

This followed many, many hours of bisecting which plugins were enabled, and still getting crashes.

Once I established that it crashed even with everything turned off, I gave up investigation and resolved to just live with it.

Expected result

That I should be able to switch seamlessly from Obsidian on iPhone to other apps and back again, and find Obsidian already loaded when I return.

Actual result

Often I get an iOS message telling me that Obsidian has crashed and do I want to report it to the developer.

“Obsidian - Connected Notes” Crashed.
Do you want to share additional information with the developer?

A member of the team once told me that iOS crash reports had so little info it wasn’t worth sending them, so I always select “No Thanks”.

Environment

Please note that I did previously verify that the crashes still occurred even in Restricted mode with default theme and all snippets enabled.

RECOMMENDATIONS:
	Custom theme and snippets: for cosmetic issues, please first try updating your theme and disabling your snippets. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community theme and snippets.
	Community plugins: for bugs, please first try updating all your plugins to latest. If still not fixed, please try to make the issue happen in the Sandbox Vault or disable community plugins.

Can you confirm if the crashes happen without Obsidian Sync enabled? Maybe test for a day of use (and keep backups on main device so you dont lose anything).

! If you do this, it will require you to reconnect to your remote vault upon re-enabling.

You can try to pause sync instead, but the better test is disabling the plugin completely.

No, I really cannot do that. I am switching between my Mac and phone all day long - sorry.

I could do it for half an hour or something like that, but not a day.

Any that you can do would be most helpful. Also, on a cold start, can you grab the contents of this on your phone? Copy to clipboard should grab everything.

Thanks so much. That should help us get started.

Also adding that some users have experienced similar in a help issue: Frequent Reloads on iOS with Official Sync - Request to Optimize Memory Usage in Obsidian for iOS

Anecdotally, it doesn’t seem to be happening as often as I expected this evening - I am at home on WiFi.

Mostly when I am at home I’m using the Mac.

And I mostly use Obsidian on the phone when I’m out and on cellular data.

Very weak suspicion: maybe use of Obsidian on cellular data is a factor?

tl;dr The latest suggestion is to Pause Sync, rather than Disable it.

I asked on Discord what would happen if I disabled Obsidian Sync, because previously when I did that by accident I found it lost all the vault sync settings, which was error-prone to recreate - and the reply from Licat was:

You are still logged in to your obsidian account

It deletes the sync state so you have to set it up again but you shouldn’t need to login again

But yes you’ll lose the sync settings
