App Exchange Not Working

I have S22+ and I am having same problem. Tmobile needs to fix all these problems.  I'm also having problem not being able to text one contact.  I did update and it worked for a couple weeks then went back to not being able to text.  Tmobile isn't reading these. They don't care. They get your money that's all they care about.  

This is the same issue I'm having,  get with it t mobile!

Most of T Mobiles  apps don't work anyway 

Wow! This has been going on for months??!!! 

S22+ user here and same issue as the threads above. Note, that I went to that app bc after going thru the regular T-Mobile app I thought, "not possible that this is it!?!" All that app option seems to do is let you pay your bill. I get an error when even trying to SEE my bill. So, when trying to navigate thru that it says I have no network connection which is how I ended up in the T-Mobile Experience debacle. 

Looks like there's been plenty of time to resolve this issue. Maybe, at least tell us where to go to find a functional app for bill pay, seeing our usage details, etc, etc... All the things that Sprint let me see in their app, or what I'm sure Verizon offers their customers to see in their app. 

Same here on iPhone and Samsung. 

T-Mobile, where's an update on this?

Same issue on Samsung S20+
Half my text get stuck and I need to reboot my phone to send them.

SAME HERE for my son's S9+

Same s20

Same, getting the error on a galaxy 20+ - kinda stinks and not a good look after the switch. Some attention to this stuff would be nice.

oddly enough if you look the one main thing all of you have in common are Samsung phones...have yet to see anyone with anything else other than a Samsung phone posting in here...
