Android 10 for Samsung Note 10+

Geez. Was very excited when I received a push notification today that the Android 10 One UI 2.0 update (Build#: N975U1UEU2BSLC) was ready for my phone (US Unlocked SM-N975U1). I then updated when I got home and boom! My phone no longer had cell service. Spent an hour resetting network settings and other configurations with no luck. I then contacted my carrier chat and after about an hour of troubleshooting and testing, I finally got cell service and mobile data back. Unfortunately, cell signal was definitely weaker compared to before the update. Mobile data speed dropped from 120 Mbps prior to the update to about 1.5 Mbps after the update. Upload speed dropped from 7 Mbps to about 0.06 Mbps. Carrier support said I will have to give it a few days to see if it improves through an update to the auto-configuration. It is so weird since I don't know who the fault lies on. But that just ruins my day.
