I’ve seen the same problem as Vlada. I haven’t updated yet out of fear of the Companion not connecting bug (still active since September)
Also quite a few phones (6S and 7) can run 15 but not 16, and 15 is still within full support from both Apple and Zwift.
The problem with hyperlinks is a minor annoyance for me, not worth the (small?) possibility of more significant breakage with the upgrade.
