Description
After moving to the next screen, I am unable to input data into the Choice or Text Box components for a while. 10 to 30 seconds of waiting resolves the issue.

How to replicate
In my app, when I make a transition to the next screen, I create a new row on a different sheet and use Relation to open a Detail Screen on a different sheet.
This has worked fine in the past, but recently when I transition to the next screen, the Form Elements are disabled for several tens of seconds.

Do you have a rough idea of when this started happening?

@NoCodeAndy I am not certain, but I remember that this event has been happening for 2~3 weeks.
