Invalid Screen + Firebase

[Cristina]

I have in my Firebase database a field with the name of the last open screen. Works with all screens except for Ventadeproductos. A message appears saying Invalid Screen

With this window it works

It doesn't work with this window even if it is the same code

This is the field in firebase

From your blocks, you are already on that screen, so you cannot go to it?

It seems in the second case that the Tag "UltimaPantalla" cannot be read from firebase and the empty list is used (ValueIfTagNotThere). Are you sure the tag exists in firebase? have you set the same projectBucket in all firebase components (and token and URL)?

I thought I had the same projectBucket, but no. Thanks
