Can't receive short codes/2FA

Ever since I switched to AT&T from Verizon I'm no longer able to receive short codes. I've been looking on this forum for fixes and have tried everything listed and it still won't work. I've tried resetting my network settings multiple times, restarted multiple times, tried to use the AT&T trouble shooting tool but apparently my device just became outdated because it isn't listed on there (it's a Moto G Power 2022), made sure the numbers aren't blocked, and I also tried going into my SMS phone settings but they're all greyed out. This is unbelievably irritating given that I use 2FA on nearly everything.
