iOS pages issue

Hello everyone I updated pages on my iPhone4s yesterday. I have been using iOS for months without any issue so I believe the new update is causing the issue. I do not know if I am the only person suffering from this issue. My sighted friend who is using it is not having an issue so I believe it is an accessibility issue. I am using a apple bluetooth keyboard, running voiceover, with the newest iOS update, and the newest pages update. The issue that I am having is that I can type for a minute or two but when I want to go back to a previous word or line, the app freezes up. When I use finger gestures, it still goes through parts of the app but the document is not accessible anymore. When I try to use my arrow keys when the text states that it is editing, no words are read even when the word count states there are words in the document. When I try to type something, nothing is read and it does not say what I typed. The document in pages becomes inaccessible and I am not able to edit my text at all. Does anyone have this issue as well and does anyone have any idea of how to fix it? I have tried restarting my phone, deleting and reinstalling the app, deleting the current document and making a new one, taking the app off multitask and starting the app again and nothing is working. Any suggestions would be greatly appreciated. Thank you so much
