Stop video ads in apps? This is not a question about blocking ads in apps - they're annoying but if I choose a free ad-supported app, it's right I should see ads.

But, some ads feature video - for instance one app I am forced to watch a 30s trailer to Finding Dory about 20 times a day. My main issue here is data usage; I'm worried it will eat my mobile data and even by broadband limits if I am using a MiFi device when travelling.

Can I have any control over what ads are played through Google Play apps? e.g. disable video-based ads?
I don't think there's a way to disable certain type of ads appearing on Android apps without using an ad-blocker.

The idea is to force users to switch to paid versions.

You may, however, choose between "personalised ads" or non, using Google account dashboard.

For me, using a VPN helps disable internet access to selected apps. This minimises to a certain extent, the number of ads I see. Also, some VPN compress most ads that I still have to see, so I save data that way, too.

I, personally, use Opera Max. There may be others, too.

But be careful, though. Some apps don't work without internet access.
