Original GitHub issue: https://github.com/AppFlowy-IO/AppFlowy/issues/8207

Bug Description

When I create sub-notes or edit existing notes on my PC (Linux FlatPak) and it then syncs to mobile (iOS) it will sometimes remove all or half the content of the note from both sides.
When I create it on PC and then check in browser it syncs correctly. It would appear that the version on mobile app partially overwrites the newer version trying to sync from the PC.
PS. I'm using AppFlowy Cloud

How to Reproduce

I haven’t been able to consistently reproduce, it happens sometimes, not others.

Expected Behavior

When I create or edit a note on PC and then later open that note on the mobile app the latest version should be synced down from the PC.

Operating System

ios

AppFlowy Version(s)

0.9.9

Screenshots

No response

Additional Context

Did some more testing, it syncs as I type without issue when both apps are open side by side, the issue only happens when I do something on PC (I always leave it open in the background for the most the day so it definitely has time to sync), then later open the mobile app after desktop has been closed.

Hi, yes I can share an example, do I just export as markup and post here or can I send it privately? I have 2 examples, one is the one with the logs, the other is from a time back, I briefly spoke to someone on Discord about it.

Yes, I think you could send it on discord to one of the members of appflowy team.

Hi,
I just sent an email to the support email address with the attachments and a second example. I used the same subject as the GitHub notifications for my email.

Quick update: Yesterday I was going working on my one page, adding content then minimizing, then adding things again and so on for a few hours. I also opened the mobile app after every edit to try and mitigate and catch any sync issues as they come up. I then noticed after the desktop app (Linux Flatpak) was open for a while (more than an hour) it seems to stop uploading changes.
I had both desktop and mobile open side-by-side and changes weren't picked up, so I closed mobile, then closed desktop. Reopened desktop, waited for the connecting bar to go away, opened mobile and it synced in perfectly right away. Considering both times I lost data I had AppFlowy open for a while before and after the changes I'm wondering if the Flatpak doesn't maybe hit some kind of time-out or server disconnect? (I'm using AppFlowy cloud in case I haven't mentioned that)
PS. Also suddenly having a crash-to-desktops which hasn't happened before, but I can't confirm if that is Gnome or AppFlowy.
