I just downloaded the latest version of Anki, QT6, and cannot figure out how to apply multiple tags to the browser. For example, I used to be able to paste tag:a tag:b tag:c in the top field of the browser, hit enter, and all three tags would be applied, but this doesn’t seem to work any more.
I see that my tag names are collecting back slashes in the top field. For example, the tag Tagalog_Lite_Lesson01 shows up as tag:Tagalog_Lite_Lesson01. I wonder if underscore is disallowed now. (edit 1: backslashes don’t show up here, but this turned out to be a non-issue. See edit 2)
(edit 2 - solved. Select one tag in the left side list, then shift>select another. This puts both tags in the top field with OR between them, like tag:Tagalog_Lite_Lesson04 OR tag:Tagalog_Lite_Lesson02)
