FaceTime Create Link Not Working on iOS 15 [Fixed Quickly]

I did all these things but still my create a link and group call options are not working.
I'm unable to accept or create group call, nor I can create a link.
I would really appreciate if you can help in anyway possible.

I have same problem

Based on the apple support that I talked, if your phone is - Hongkong, China or Vietnam Variant this feature is expected to not work on any iphone users since based on what I understand they follow guidlines of this country. So better check where your iphone is manufactured.

The turning off restriction method worked for me !! now i can also share my screen. thank you so much

question, can i delete a facetime link out my log that someone shared with me? because it keeps showing on my upcoming calls.
