Mine previously suddenly cant use. Cannot load. Then i call their service hotline, they say need go down to the bank. I go to the bank, the person see see, say my phone no network. I literally, uninstall, then install back in front of him, then he see see, take out his phone and say, his phone no problem, means my phone no data.

I gave up. Once in a while try. Once i waited 30 minutes and it manage to load. But every time i tab out of the app and go back, everything freeze. I think is just the app useless. I was using samsung s23 ultra btw.

This was last yr or longer. Not sure which android, but i always update to latest available and I'd think s23u should be quite updated.
