Yes. You don't get removed from the beta program, so whenever the next play store update rolls out it should update

Will i be able to upgrade from Google Play after that

Solution that worked for me on Android for problem reported [here](https://www.reddit.com/r/whatsapp/comments/123x7ku/whatsapp_beta_update_error/). No data loss.

1. Install APK downloaded from the official site. (Package installer, Not play store) https://www.whatsapp.com/android/
2. It will *update* the existing app to the latest with bug fix for expiration date check.
3. Restart the app by force stopping or restarting phone

Solution for those still affected by expiration date bug
