I encountered a number of issues with iOS apps after upgrading to iOS 13:
- Books - the ebook (ePub format) can’t be opened; it works at the beginning but suddenly it can’t Be opened any more; when I clicked on the book, it simply doesn’t open; no error message; interestingly, PDF format ebooks can be opened as usual;
- Files - when I browse the image files I stored on iCloud, it just shows a blank screen with the file name; see attachment;
- Numbers - when I tried to open a spreadsheet, it simply said it can’t be opened; see attachment.
My ebooks, files and spreadsheets are all stored on iCloud or with iCloud enabled. It happens on both my iPhone and iPad Pro. I need to restart my iPhone/iPad Pro and then it will work again but after some time, it starts not to work again.
Im not sure if it is a problem with iOS 13? iCloud? Or the Apps? Anyone has same issues and have any solution?
Btw, I’m using an iPhone 7 and an iPad Pro (1st Gen, 9.7”). Both with latest 13.2.3.
