Power apps list data validation failed but no validation setup in the app

[krzydec]

Hello. I build a simple Canvas type App using one of the templates. 

The app is linked to the SharePoint list.

It was working fine until this morning when I started getting a data validation error when I'm trying to create a new entry from the PowerApp on the tablet.

I checked SharePoint list settings and none of the columns has a data validation set up. Besides that when I entered exactly the same values using SharePoint via a web browser or via Teams desktop app the new entry on the list was created without any problems and it's visible on the tablet.

Has there been any recent change of password in your SharePoint?

Hi, no recent password changes.

UPDATE:

The app started working now without me changing anything.

Is anybody able to shed some light on this problem?
