Manually prock ads and have a countdown for how long an add is needed to access the service for free.
So basically I understand you need the ad revenue too keep the app a free service. But the ads have made the app way too glitchy. Sometimes they don't prock properly and the app freezes, sometimes they do prock but they prock behind the app, never end and make the app super laggy, sometimes it doesn't register you've watched an advert and makes you watch 4 in a row, sometimes the app can't handle the data load and just crashes. Basically it doesn't work and has made grindr semi inoperable. Even if you pay for grindr extra they still ruin the app.
My idea is that if you press a button it manually procks an advert and gives you 4 hours of free grindr and you could watch 6 a day so you can watch them all in one go.
