I’m getting this too. Initially it seemed to be resolved for my users when I installed the AppSheet update 12.7.2, but it has started happening again.

@praveen @Aleksi @MasterCode_Consult I’ve submitted a brief support email to AppSheet asking for assistance with this issue. My users are still having problems. Need advice asap

I also have this issue across 3 apps and 80 users since i reported this at 10:30 this morning.

Guys, please can we have an update??


@praveen, @Aleksi,

Now its seems to be syncing again… I don’t know what you guys did, but it fixed this problem. Thank you so much for your prompt support…


Some of my users are still having problems; for others it’s working fine. Any updates?

Same here, mine still not working.

We are working on a solution.

Quick check … we believed the change that caused this problem was only rolled out to a subset of free accounts. If you observed this problem today, could you please let us know if you were using a paid account rather than a free account? Thanks

Hi Praveen, ours is a paid account.


Hi Andy,

Quick question, are you on pro/premium plan or do you have the business subscription?


I’m on a paid account (business subscription)

Hi Billy

We are on a business subscription.
