is anyone having network issues with galaxy z fold 3??

Okay so I've followed this forum since beginning of March when I started having issues on my fold as well. I did the workaround for a while and found it to work without many issues. But I finally got sick of it and wanted my service back like it was supposed to be. My fold is the 512gb unlocked version directly from Samsung so tmobile couldn't help me. I first believed that it was only software issue. Because before software update it was fine. So I was heavily leaning against it being a hardware issue. I am an advanced user so I started by downgrading the device back from android 12 to Android 11 with older security patch. Still same issue. Swapped Sim cards, even my Verizon didn't work properly. Nor AT&T. So then I downgraded the device all the way back to the android version that came with the phone when it was released back in August. Still same connectivity issues. I'm sorry to say but I am now a believer that it is hardware issue. Something in that patch destroyed the internal modem inside our phones or the antenna. Not sure but I decided not to open it to try and find out. After unsuccessful attempts and downgrading to multiple different unlocked and tmobile versions of Android, I finally gave in and decided to ship my device off to Samsung in Texas to have it repaired. 😔 I'll update when I receive it back as to what verison I'll have when I receive it back. I've tried all the baseband versions BVA9, BVAC, etc etc tmobile and unlocked USA versions to no avail. Good luck guys. Next time I think I'm going to buy the tmobile version from tmobile and not Samsung. Only reason I didn't was because at the time, tmobile only had a 256gb version which was not enough for a power user like myself so I bought the 512gb version unlocked from Samsung and this nightmare appeared.
