It looks like we are experiencing two similar looking problems with different causes.
At the end of November login at support.ptc.com was normal but login at the community vastly delayed. Then Lithum restarted their server, as @Jaime_Lee explained and the problem seemed to be fixed.
But since start of December (PTC Maintenance weekend) ist the login at support.ptc.com which takes over two minutes.
Is there any explanation for the fact, that the problem still isn't fixed (other than "what do you expect, you're dealing with PTC")?
Hmmm, I just wanted edit my post to fix a typo but I am not offered the option to do so!
Whats going on here???
Instead I am offered the option to move my message - an option I was not aware of so far!
I don't care about the "move" option but I still would like to be able to edit my post!
