Reward Bug with Ads

Hello,

when I choose to watch an ad for another attempt at an event, free seed packets, or 2x the rewards, I am shown the ad and watch it until the ad finishes or gives me the option to skip the remaining portion, but an exit button (an ‘x’) never appears and I am forced to force exit the game because there is no way to get back to the game. 

Steps: click option to watch ad in exchange for [reward] —> watch ad either in its entirety or use the provided skip button [if applicable] —> ad screen with download button is visible —> no exit button is ever seen and there is no way to get back to the game —> user (me) is forced to force exit the game and restart it.
