Login is broken since latest update. If i switch to API Key it is not saved, in fact i saved it correctly. when i open the addon settings its on user and password-Login again.

A recent update has broken username/password based sign in. Thankfully, I eventually tried generating an API key and found that extension support for that was still functional! However, it's kind of crappy to have my extension suddenly log itself out and then refuse to login until after I'd found a workaround to the introduced bug. (FWIW the error was the very descriptive: "Something went wrong, try again please.")
