I have been having this issue for a long time, it started with my Galaxy s10 i got when it was first released and had up until May and around December it started to do this and carried over to my s22 ultra. Certain apps like YouTube and Tik Tok as well as a lot of websites like Pinterest wouldn't connect to the internet when using my mobile data. I chalked it up to a DNS issue and started using Google's DNS server which fixed that issue, except for when using public networks and the DNS server cant be accessed, but at this point I'm at a complete loss on how to fix it permanently. I reset my s10 completely when i was still using it as well as my s22. I've been through multiple different DNS servers which worked on the phones end but when I tried to use my hotspot on my laptop and iPad and the issue carries over, cant use certain apps or access websites. I don't know what could have caused this issue i haven't ever messed with my settings and i can't pinpoint an update that could have done this to my phone.
