Technical bug regarding cellular data

Every time I launch mobile Hearthstone (polish language, Europe) the “Cellular data” option in “Downloads” is unchecked. This means that if I don’t have a Wi-Fi connection, I won’t be able to download any updates or play the mobile version of the game because I’ll get errors like “Checking for the latest game updates, try again later” or “Couldn’t find version information. Check your network connection.” This hasn’t been fixed for months or even years now, what the hell? I can’t even send a ticket to technical support because there’s no option - I am told to post on community forum but polish community forum has been dead for years now… You really want our money but you can’t even fix a simple bug for years? This is absurd
