pdf-notes for Android

I’ve loved and used this app exclusively for years, my entire brain is on this thing. However, now 8 cannot access any of my PDFs- clicking on them doesn’t elicit any sort of response, when this is how they usually open.

I have been using it since six years ago it is wonderful

I have had pdf-notes for six years and I can’t use anything else. It does have some major flaws, such as not very pretty design, inability to make selections and transformations, and occasional glitches. However, pdf-notes has really easy to use tools, lots of export options, and the ability to rename and organize pdfs. It is so simple and I love it. None of this Notability stuff, pdf-notes is the OG annotation app. However, pdf-notes, if you see this, please do consider updating your interface to something that doesn’t look like it’s from 2012, and a transform/selection feature would be amazing.

Since the most recent Google update, I can’t access my files. I can navigate my files but when I click to open they will not open. They still would not open. Then I had the idea to add something to the app. I was able to do that and now it is working again. Thank you for getting back to me. I couldn’t find where that was after restarting my Mobile.

In Google store, it still the state that I didn't buy this Google even though I already paid 9.99$ in this free trial app. so, I wonder that are these different things between Google store 9.99$ thing and 9.99$ in free trial version thing? I prefer Google store thing, could you please change the state like I bought it in Google store ?
