The more direct approach if you’re rooted: use App Manager, find your app, click the “X trackers” button in the header and if you still see adverts, look for any activities, services, receivers, that look like ads (usually highlighted).
For example (german):
There’s also Warden, which can do the same but more simplified. They use both Exodus Privacy.
They both edit the app directly, without any background services or VPNs.
If you’re on Android, go to settings and network, find and enable private dns mode using this host address
dns.adguard-dns.com
It should block the majority of ingame/inapp ads, etc
Edit: Minor Caveat. This isn’t fool proof nor is it 100% effective.
But takes you all of 30 seconds and does not require root permissions, side loaded apps, etc. Its all about the cost benefit ratios.
