Apps built from Thunkable are crashing

Dont know what is wrong here.

App is running properly 1 minute and next minute the same app without change of any code is not working at all… what’s wrong with thunkable ?

Also An app which is once built up and is installed on phone, does it has anything to do with Thunkable code or sites ? If no then it must be air-table which is not functioning occasionally.

Found one more observation, App is working under Test mode but not in App mode. (same code, nothing changed at all). what can be the reason. same mobile and everything.
