iOS (iPhone) Endlessly Reloading Vault

Twice now, during the few months I’ve been using Obsidian, the iPhone client has become stuck in a loop of constantly “Loading Vault.”

This will happen every 60-90 seconds, or immediately after I paste a picture.

When this happens, it either erases the changes I have just made in the active note (if any) or doubles up on changes recently made by adding them in again.

How can I prevent this from happening in the future, and how can I stop it happening now?
