I have never seen that. I am not sure what it is. The zaps only get deleted if the app is running to close to the memory limits and has to delete something to keep running. 🤔
Oh and this happens all the time while I'm responding to someone (idk why). Everything jjsy disappears. Never happened on the .apk version

currently running most up-to-date version, android (graphene)

I've noticed this begins to happen when the note is in draft mode
Hmm interesting 🤔
hum... For new notes or just replies?
Extremely consistent for drafts (both new notes & replies)
On occasion for immediate response
Again only from updating to play store version on github
