Lately, you are put in ads that have become intrusive instead of inline. I end up closing the ad before I even see what it's about, which is no good for either the advertiser or your app. Your ads should be in line only, such as appearing at the bottom of the app as some do. Ads that interfere with the app, I shut down the app, and they remain unwatched.

This app used to be really good, then they added a bunch of full-page ads. That was a problem but could be dealt with by getting a premium subscription. I did that for over a year. What made me stop using it on 3 of my devices is actually that it made all three devices extremely unstable. Apps wouldn't respond, they would crash, one phone was lagging to the point that I nearly went and got a new phone. Turns out it was this program. Won't be back.

Hi Brad, Sorry for the inconvenience. We have fixed this problem, please update to the latest version and check whether the problem still exists. Wish you a lovely day!

I didn't have any problems with the last version. The upgraded version is awful. It will play an Ad after every single thing you do which it didn't before & once the Ad plays it kicks you out & sends you to play store to install it. The only way you can get out of it is by closing it which sometimes takes several attempts. I've had this for years but it's not worth the fight & frustration. . NEW PROBLEM! Woke up today & all my pics are gone!! I was in the middle of backing it up. Lost everything
