Proxy auto config didn't work on beta versions of iOS 15.
But today I upgraded to iOS 15 (release candidate), but proxy auto config still doesn't work.
Previously, I didn't submit a report on this, because I didn't know where to place this report (in the Feedback application). Thought someone else would send this report.
Now I can't send it, because I deleted iOS 15 beta profile.
Tried turning off the private relay but it didn't work for me.
This bug is also observed in iPadOS 15 (release candidate).
P.S. Sorry for my English.
