Trouble importing playlist

Hi, I'm running Android 6.01 on a Barnes & Noble Nook HD+ that is replacing an old one with same OS. I made a backup and transferred via Bluetooth.
If I click on the links in the file I get page not found. Google Drive does not offer Ireal as an option. If I open the file in File Commander with IReal, the import starts but stays at 0%.
I was able to transfer the playlist using the sandbox so all is not lost.

I did see a previous post about the mail client being a problem but the import stuck at 0%???
Thanks

Any resolution?

No, tried on 2 different Nook HD+ with 2 different builds Android 6.01 Cyanogen Mod. Sandbox works fine so no big deal.
