Hi All,
I am trying to copy an Application in APEX 21.1 using the Copy this Application link. I have done this many times before using this application in all previous APEX releases with no issues.
However, I am now getting the following error when using the copy process (I also get the same when exporting and importing the application.).

I am working with my hosting company (MaxApex) to resolve this and we have tried the 'known error' changes such as entering shortened Application and Application Alias names. Also clearing the Application Comments. None of these has worked.
Right now, I am unable to clone my environment(s) to create new dev/tests or restore them. Unfortunately, I cannot load to apex.oracle.com as also get the same error!
This looks like an issue with 21.1 or a bug. Please advise.
Cheers,
Jim
