Your STRM file will be calling plugin.video.gdrive and not plugin.video.gdrive-testing, so add -testing to it for testing with the testing version.

When you install the -testing version, you should copy the settings.xml from the non-testing version over to the -testing useraddon plugin directory so you can reuse the same login accounts you've already setup.

I'm tried it with 0.8.5.2 version and it works perfectly.
Kodi is asking me if my default stream account is correct, but that is less than nothing problem

Thank you for great work!

I have another question about Rclone and encrypting files at drive.
is there a possibility to encrypt the files "on-the-fly" in kodi/gdrive-add on ?

Do you mean decrypting rclone files on the fly? Not without the author of rclone documenting the encryption details.

The plugin uses decrypt on the fly for crypto.
