I've noticed a couple of problems with BLA 3.2.1:
1. It doesn't remember your username/password anymore but instead gives the error
"Validation failed: -- 125. The token is invalid. -- 'Session Id' should not be empty.". This doesn't seems to be time dependent, i.e. after logging in I can select "Quit" from the menu and re-launch and this comes up right away. This happens regardless of whether I use my username or email address.
2. "Check for Updates" never comes back with an answer.
[Edit] - So the above behaviour is true for my desktop, but my laptop works fine. They're both Windows 10 1803, but the desktop is Pro and the laptop Home.
