AppSheet editor

I can no longer use Appsheet editor on my iPad using any browsers.

my iPad is running iPadOS 18.4.1 (22E252) and it was running fine until a recent s/w update.

the appsheet editor console loads ok but when I select any of my apps it will not open with a ‘cannot open page’ error.

everything works fine on my Mac. This issue is only when I use my iPad..

I have followed all online suggestions but nothing has helped.
