As noted, this is a VERY HUGE issue and needs to be the #1 Propriety of Grindr to address right now.
No ad should have sound enabled for any reason, leave it up to us to choose to listen to a specific ad if we want to.
At times, multiple ads sounds will play at the same time.
It makes it impossible to trust Grindr when you don't know if it will "out" you because of ads automatically playing sounds. You cannot open Grindr in a quiet area for fear of loud sounds from the ads, especially porn ads. The mute "button" rarely works in the first 2-3 seconds after the ad sound starts. It feels as if Grindr is trying to force us to buy ad-free subscription to fatten their pockets instead of making a safe environment for guys to meet other guys.
Disable all ads until mute is the standard setting for all ads and the ad can only be unmuted manually instead of only muted manually.
