Can't revieve text messages
I previously used next sms as my preferred texting app on my galaxy 22 ultra but I recently switched to the pre downloaded ones on my phone I started with one and I am not able to send messages yet I can recieve them.. so I switched to the other, I can send messages yet I can't recieve them from MOST people. So fat messages have come through from 2 people in the last week of trying to figure this out. I also CAN recieve picture messages and gifs. I tried every trouble shooting thing I could think of and also that at&t chat told me to do along with customer service for the app itsself. Please help!
