I cleared my browser cache multiple times on both Firefox and Chrome before posting here (I mentioned it in my post above).
What seemed to work, for reasons I don’t understand, was making two separate redirects: one from bardicfool.com –> bardicfool.com/411 and one from https://www.bardicfool.com –> https://www.bardicfool.com/411. Now the redirect works on both mobile and desktop. I also had to wait awhile (maybe a couple of hours?) before all versions redirected correctly.
I’ll mark this resolved, but the troubleshooting info’s here if anyone else ends up needing it!
