“Couldn’t save content. Check your internet connection and refresh the page." on iOS mobile app

That’s because those web browsers do not have the “Reader View.” Safari is the only web browser available on iOS devices, that has the “Reader View.” The “Reader View” allows you to create a PDF of a webpage, and then share it to various resources.

For example, if I’m reading an interesting article either in Safari, or my Yahoo Mail, Twitter, etc., I will click “Reader View” to create a PDF of the article, and then Share it to the Dropbox app on my iOS device. This has been working fine for me until this week’s update to iOS 173. I feel like Apple and Dropbox need to actually communicate with one another (imagine that!) and work together to resolve this issue.  Part of me believes this issue is with Apple (since this worked fine for me until the 17.3 update). Part of my also wonders whether Dropbox needs to update its app after the iOS update. Dropbox has not updated its app since the iOS 17.3 update. But I feel Dropbox needs to reach out to Apple on this, share with Apple the screen recordings we have shared with them and the complaints they have received from us, and they can work together to figure this out.
