Since 1.1.24 I am not able to login on Win10 (64bit) with latest Kodi.
"No credentials have been set or the login failed.
Please enter your credentials in the next settings dialog."
I haven't changed anything, so my login data should be correct

Regarding the first issue: I should notice that I am using login via facebook credentials with 2 way authentication. While I usual use PASSWORD+2way-Code on my ODROID, I used an own password on Win32 because facebook sent me an digit-passowrd via sms for spotify app. In the past, both ways work, since ~1.1.24 both logins don't work any longer :-( So the addon does not work at all :-(

I don't think that is going to work with the librespot implementation.
You should probably create a device password... Log in to your spotify account where you can specify a password for devices.
In that case you can login with your spotify ID (which is a number) and that password.

Oh, interesting. Before ~1.1.24 it did work via facebook-login. However, thanks for your solution!
I just needed to go to spotify.com-account and create a device password (via https://www.spotify.com/us/account/send-...-password/ ). With digital username and this password I was able to make your addon work on my Windows 10. This evening I will try on my ODROID aswell.

Another issue: When I close Kodi, I get a error in my log (windows 10 64bit, didnt test it on libreelec etc.).

Fixed in 1.1.29

Ty!

And a 3rd "issue":
Whenever you update your addon, I need to update the cache-files on my ODROID (via Windows trick, because no browser on ODROID). This is not nice, but it is ok. However it is annoying that Kodi tells me every some less minutes that I need to "authorize this app on Spotify". When I hit "ok", the message disappears and appears some less minutes later again... At the end, I need to disable the addon or do the authorisation via windows trick (copy cache files), otherwise it is not possible to enjoy watching a moive with this popups

Hmm, it shouldn't need a browser at all on Odroid.
Can you grab the kodi log from the Odroid device ?

Also, I don't understand what you mean with updating cache files ?

Maybe this issue comes with the fact, that I tried to login via facebook-account and two-way-authentication. So maybe this is obsolete, since I changed to device-name/password. I will check it out at evening as well and provide a debug log file if it fails.

For your question: Once you updated your spotify addon, I had to update the cache-files also (create the cache files via win32 and copy it to the ODROID, because it has no browser to login).
