Issue on UX Button, please help me

can anyone help me, in the past few weeks I have found it very difficult to access the appsheet on the mobile view, especially when I want to use the UX button like “Adds, Update or Delete” the UX button often does not appear in the input form or will return to the “starting up” view or also loading takes a very long time. what happened to AppSheet? I have used AppSheet 1 year ago until now with a PRO license, this is very frustrating for me

Please contact for help with this.
