I’ve used the app for many years but now it’s only gotten worse. The sticker option leaves residue on photo adjustments. Goodbye.

Purchased the upgrade years ago and was great for the small jobs I would do. Tried to edit a picture (add a quick watermark) and the app wouldn’t launch. It was continually stuck in the splash screen. Tried and wait it out and the app wouldn’t launch crash. Since I have updated my iOS and even phones thought it might be an issue. So I deleted the app along with the data since I had bought the upgrade years ago. Downloaded the app again, and this time it launched but to my surprise? It is now a monthly subscription?! I tried to restore my purchase and it says I hadn’t bought anything. This is when I realized what has happened: lock out the legacy purchasers to make them pay the new monthly subscription model. For these prices, I would rather switch to photoshop express. Too bad, this was a great app for very casual users. I don’t need anything AI (I believe the selling point because of the tokens used). 2 stars because i had been using it and it’s great for SIMPLE edits
