License Merge doesn't work

Yes. When you buy new licenses you can merge them into an older key.

It is a confirmed bug. We are aware of the issue and working on resolution

This issue has been resolved.

Hello we still have the problem the message is after we have selected the master license and then the newly purchased: "Something went wrong"

I'm also encountering this issue.  When selecting the key to merge I am only directed to a webpage frame that says "Something went wrong".

We are looking into this issue. It seems it has re-surfaced.

This issue has been fixed. The fix will be deployed shortly.

Thank you!  I can confirm this worked for me now.
