Thank you so much, the empty navigation link works for me as well. The behaviour is still present in the current iOS 14.6 beta.

I have the same problem! The downloads work on my Mac mini with macOS Sonoma beta but on my Mac Book Pro with macOS Ventura 13.5.2 I only get the 404 bad request status. I tried it with the App Store version, the direct download and the previous RC version. Nothing works.
