iOS 14 PDF viewing

After few hours searching on internet I found a solution. First of all I need to keep Viber for family needs, so it was not option to delete it. This is solution that worked for me:

1. Install iBooks app on your iPhone
2. go to your iPad and use Airdrop to send pdf file to iPhone
3. on your iPhone you will get notification that ask you how do you want save your file (see attached screenshot)
4. choose option that works for you, I chose Files

this worked for me. I hope it helps you.

I am having same problem. PDF file shows as sent , but than opens Viber app and when I cancel it, file doesn't get transferred from my iPad to iPhone. Both devices have the latest software.

Update to iOS 14.0.1 and check again.
