I’ve got a problem with Hearthstone on my Samsung Galaxy A3 Android Phone (Android 8.0.0 running) :
The game app take about 3Go after the first download, when i can play the game for the first time. I immediately disables extra downloads in the game menu, but even if i can clearly read “Download disabled” in the menu, the app continue to try to download extra data (at least 2 extra go, and then i run out of free space and i can’t see it he tries to get even more or not…)
The bug is quite recent, no more than 1 month, i played for many years without problems before that.
