Lost download feature in Kodi 17?

Updated Kodi on one of my android boxes.
Installed the same add-ons no problem.
but – the download feature in the add-ons don’t work.
I can set them up the same by enabling them and setting a path, but all come back saying ‘stream not available’. (even though I can stream no problem).

doesn’t matter what add-on I use.

I have gone back to kodi16 and the download feature works in all the add-ons with out an issue.

is this kodi trying to block out stuff – or is it a glitch?
