How to edit the default.aspx page at a Project Online site?
spoguys You want to look a change Microsoft implemented to remove custom scripting from OneDrive and SharePoint as it may be related. You will need your Global SharePoint Admin to go M365 Message Central and review Message ID MC714186. Basically, they will need to run a PowerShell script to re-enable custom scripting on affected PWAs. In our case, we would add new fields to a PDP then save it, but when we revisited the PDP the fields were gone. Running the script fixed the issue.
I am pretty surprised that I don't have permission to update the page as a site collection administrator:
Maybe it is some latest changes that Microsoft made recently.
