- Only a single Win 11 desktop (full vault) and a single android phone with some folder exclusions. It only disconnects on the Android device, and is preceded by the usual obsidian indexing (as per other poster).
- Definitely no other synching involved at all at either end (I think this would only really be an issue at the android end anyway because Sync itself is not supposed to touch Sync settings locally)
- Not sure how path on desktop is related but it is X:\Obsidian\My Notes
- The indexing alert is just the usual inbuilt obsidian toast that comes up with regular indexing nothing to so with Sync or any plugin
- Not sure how to get to debug info but I can’t now because it is now transferring thousands of files that were previously in excluded folders (this is a more general problem that when you link to an existing remote vault the popup does not show the folders on the vault in the popup to exclude them, and the only way is to type each path manually - but on the desktop you can do this - on Android I have never been able to enter any non-existing path even though it says you can - so regardless of the specific issue here this is always a problem when connecting to an existing remote vault when you want exclusions - it is basically impossible to do (at least for me) without letting the whole remote vault synch, then doing the exclusions and then deleting the many folders that should not have been transferred in the first place.
I know this is a meta-comment, but frankly Sync, as a paid service seems distinctly untrustworthy in comparison to the rest of obsidian.
A clue might lie in the obsidian alert above - obsidian may be switching functionality like Sync off while it is indexing and then not restoring that stuff on again (perhaps if that functionality is it is accessed during that time?).
On related lines the indexing (as per the toast) is only supposed to happen once. But many people are finding that it happens over and over. And in the thread discussing that, it was closed and blocked when one person happened to find a solution that happened to be relevant only to their situation. Obsidian keeps indexing notes when starting up
Given that the reports indicate a common conjunction of the vault indexing (which it should not do at all according to the indexing popup itself) and the dropping of the sync connection - I suspect that the first bug is facilitating the second.
And as pointed out in both posts regardless of anything, a sync which is no longer connected - but does not point that out anywhere other than in the settings (regardless of the cause of that disconnection) is a functionality bug.
