I am not able to create custom form for any list across the whole tenant and getting the error:
"Could not save the list changes to the server".
I am working in SharePoint online and using SP Designer 2013. I am the site collection administrator.
It was working before and stopped working a few days back. I have tried following things but the issue is yet not resolved:
1) Checked "Allow custom scripts" from admin center.
2) Add and customize pages permission is granted.
3) Cleared designer cache.
4) Checked using another site collection administrator account.
