My App/Pages Support link:
Describe the bug:
“Save” button does not work in the action editor
Changes applied, action editor window closed, return to designer mode
How to replicate:
Open any custom action by “Edit Action” link and try to save
Loom | Free Screen & Video Recording Software
Does it work if you try another browser?
If not, please submit a ticket.
I had that problem before and the only way to fix it was by duplicating the app. The copy stopped having the issue with saving custom actions.
Thank you, Grumo!
Making app duplicate really helps. Seems duplicating is the only way to solve the problem.
