I’m currently running 3.3.0.beta4-dev (16a8a31c52), and the latest version of tag banners, which should be 9afa40b, but I don’t see a way to verify this within Discourse other than it saying it is running the latest.
Enabled settings in tag banners are:
show on mobileshow tag descriptionshow below site header
With the theme component enabled, if you go to a category, filter to a specific tag, then press the new topic button, it opens the composer with the correct tag but with the category set to the general category instead of whichever you were in. This happens in every category that I’ve tested, both public and private. This doesn’t happen if no tags are filtered to.
