Hello all,
We have an issue with ios16 where guest access is not working due to failures at the redirection phase. This issue happens only with iPhone while it's working totally fine with Windows or Androids.
After some checking and troubleshooting we found that there is a behavior change starting from ios16 to use public DNS servers instead of the private ones. This is mentioned here:

We already had a case with Cisco TAC but they ended up recommending us to reach for Apple support since this is an iPhone issue and ask for a fix but this seems like a dead end to me.
I was wondering if anyone else faced this issue? and the recommended way to fix it?
Best regards,
Tariq
