Ads are shown constantly. I couldn't even find 1 notification sound without having to close a single TikTok ad 4 times, then an ad from Zedge asking me to pay MONTHLY and not a single purchase to remove ads. The price is cheap, but it's easier to just look up "new notification sound" on Google, download a sound file, and use that. Used to be a great app and I've used it for years across my phones, but now it's just not worth it.
