Intrusive adds and inability to restore purchase makes app nearly worthless

I upgraded to a new device and purchases were not automatically restored. There are no settings for this app so the purchase and restore options are hidden behind a tiny remove ads button. This takes you to a page to purchase themes of some sort. The restore purchase button is there but you cant scroll to it and tap before it springs off screen. While doing all of this you are still subject to full screen ads every 30 seconds which makes using the app pointless.
