This reminded me of an older app that fahbil created back in 2018 for Android. But I think yours looks better.

What I noticed is that if you click on one of the quote links, the app takes you to a blank page with nothing than the blue background on it. Perhaps that's something you can look into.
There is a thread in Meta that compares Bitcointalk and Altcoinstalk. The OP of that thread gave an example how Altcoinstalk has a button you can click on to copy a whole quote/code for easier pasting elsewhere. Maybe that's something you can do as well.

Great initiative with the app, thanks for creating one. The biggest issue with using the forum on a phone remains quoting to and editing parts of someone's post. That's never going to be as easy on a phone as it is from a computer because you have to make the selection with your fingers.
