Can't play on mobile data

Since the update in May this year I have not been able to play while using mobile data, I can only play when connected to WiFi. Ive seen many people report the same issue since then and I thought it would be fixed by now.
Used to play while commuting or during breaks but am never able to anymore.

What do you mean you “cannot” play?

Do you mean you literally cannot play, i.e. the game doesn’t start, or the Play button is disabled?

Or do you mean that you can play, but its not worthwhile because of frequent disconnects?

No I literally can not. The app opens and shows the tavern doors but that’s it, it just stays loading on the tavern doors and does not go past there.
