hey there! you may have an old version of the client cached due to an intermittent issue we had with deployment. to fix this:

  1. delete the apk cache

on macos: delete the ~/.expo/android-apk-cache directory
on windows: same thing, find and delete the .expo/android-apk-cache directory (maybe in C:/Users/YourUser/)

  1. run expo client:install:android

1- Re-install Expo app on your phone
2- expo upgrade

Congratulations!!
