Anki 26.09.2
MacOS Tahoe 26.5.2
We’re going to need more of an explanation of the issue you’re seeing – what led to it, what behavior you’re seeing, what you expect to see different than that.
But before you respond about that – try everything on the Troubleshooting Checklist.
I, too, am confused by what you meant by “can’t auto resize”. I am not sure what behavior you think should happen or what behavior you currently see.
(The behavior that I see with Anki 26.09.2, macOS Golden Gate 27.0, is that each profile seems to have its own saved window sizes. For example, if I am using Profile A and resize the Decks window to be tall and narrow, and then I switch to Profile B and resize the Decks window to be short and wide… If I switch back to Profile A, the Decks window is tall and narrow. If I switch back to Profile B, the Decks window is short and wide.)
