Hi guys, been experiencing the rainbow / spinning wheel on my Mac with Thunderbird since I switched to Mac. I do have a decent machine with M1 chip. Thought that it was due to having a few accounts but then reinstalled Thunderbird and tried with one account only and it does the same thing. If there is no account connected to it, it loads right up. And it was working fine on Windows (loads up quite fast).

Is anyone else experiencing this? Any solutions to make the program startup better? It feels like it will freeze the computer...
