Due to a quite unfortunate bug in Little Snitch 6.2.1, automatic software update checks may not work for some users, so they aren’t notified about future fixes and updates anymore.

If you are using 6.2.1, please perform a manual check to get 6.2.2 which fixes this issue.

Please boost to notify others who might also be affected by this bug. Thanks a lot! 💐
