Flashing red

Love this app but the flashing red email link to advertisements makes it unbearable

Unable to restart a level

Obviously gone wrong on a
 Level but there’s no option to clear the board and start again. Very frustrating

Invasive ads

I’ve had this app downloaded for years. Today was the last straw. I looked away from my screen for a second and didn’t realized an ad started. I tapped on my screen to avoid my phone auto-locking. Well, I ended up clicking on an in-game ad which redirected me to God-knows-what kind of link. I really hope it didn’t download anything malicious.
