suddenly I lost the "turn on/of improvements butto...

I'll try a short story:
1. 2 months ago, I started using a normal appsheet
2. Then I installed the Appsheet Toolbox plugin to increase the capabilities of "Expression Assistant" and my normal for a month
3. Approximately 48 hours ago, suddenly all "Expression Assistant" disappeared without any "turn on/of improvements button" in

what I did:
1. Have cleared the cache on Chrome
2. I have changed computers but the email is still the same

still doesn't return to normal "Expression Assistant"

However, if I move the app to a different email, it turns back to normal

Is it because my email account has a problem?

please help friends

When it's still normal it's really comfortable to use
