Some features aren't working when running [Nov 2022]

Bottom navigator and the animations are showing when designing but not showing when running. But the buttons from the navigator are working even though they aren’t visible. What could be the issue? How to solve it?

Where did your animation come from

What file format are your button images?

Animations are *.json. They are uploaded to media files of thunkable.
The images are png.
These worked fine a week ago. But not working when I opened it yesterday.

Can anyone help me?

It’s working when I change the position to “Relative to screen”. But not working in “Relative to device” which is what I want.
