429 Too Many Requests

I encountered a number of issues with iOS apps after upgrading to iOS 13:


  1. 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;
  2. Files - when I browse the image files I stored on iCloud, it just shows a blank screen with the file name; see attachment;
  3. 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.

I understand you are having issues accessing your data on iCloud. Since the screenshots that provided were taken at the same time, it's possible there was a disruption in the iCloud service at that time. If this happens again, click the link below:

Hi m_tai,


Thank you for the additional information. Based on the information you've provided, I think contacting Apple Support may be the best way to troubleshoot this issue.

Take care.

First, thank you for getting back!


I now believe it should be an iCloud issue as a few other apps seem to have issue with files on iCloud too.


But first, the iCloud is still working when I have these issues. For example, I can still browse into different folders in Files but only when I try to open the files, they can't be opened.


Second, the ebooks that I can't open are exactly ePub books. As I said, I can open 'some' PDF books in Books. May be those get stored locally on my iPhone/iPad. But the point is that the ePub book should also be stored locally, as I was reading them, like, in 10 min ago, and then after I closed the book and then came back to re-open it, it couldn't be opened anymore.


And the only remedy now is that I have to restart my iPhone/iPad. Once I restarted, I can access the files again!


Besides, the screen captures in my last post were captured when I posted here. It is still happening now and I need to restarted my devices if I really want to get to the book or the files!


Hope the above clarify the situation and grateful for any further help!
