I am currently using macOS 11.4 Big Sur and Safari is version 14.1.1 (16611.2.7.1.4). I have been using my laptop for a while and it is quite stable, thus I don't have a plan to upgrade my OS.
But today when launch my Jira Cloud from Safari, I noticed that the UI is TOO BAD! And if I switch to Chrome, the UI is back to normal.
I am not sure if Jira Cloud is still supporting Safari 14.1.1 or not, but it looks like a compatibility issue.
Is there anymore know what is the problem?
