Broken Ads. Every third ad freezes and causes you to lose all current progress. This game is clearly balanced with the requirement to hit every single ad so its unavoidable and game breaking. Very disappointing. Updated 2/9/22: logged in to the app to find all progress deleted. Have to start from scratch. Updated 2/12/22: after the last wipe of progress was fixed, woke up today to have my tournament progress completely deleted.
