There seems to be some incredible bugs dropping through the Appsheet system at the moment.
One of the latest to show up is the inability to restructure table schemas if ANY of the tables in your app are set to be READ ONLY.
It may be just me and my apps, but the dreaded error below will show and you will not be able to save your changes.
I don’t know if the error affects different data backends, it is Google Sheets in my case.
I have a work around to set the Tables to READ ONLY without triggering this bug and that is to use the FORMULA setting and provide a text string “READ_ONLY”.
Once you update all your READ ONLY tables to include a formula and save, only then will you be able to make any schema changes to other tables without the bug appearing.
There is a massive caveat if you are previewing the new GMAIL integration as it seems that a brand new INVISIBLE table has been added behind the scenes to deal with GMAIL EVENT ATTACHMENTS.
The above table does not show in my App and I believe it is for the GMAIL EVENT stuff that is broken as well.
So consequently, if you are developing and changing schemas in apps that have this preview enabled then you will NOT be able to make any more schema changes because the above table is set to READ ONLY and is invisible so you cannot do the workaround.
Hope you find this information useful in these current frustrating times.
