Tunein radion is great. The only problem I have with it is that I can't get my local station. I can get them when using the addon within a browser or directly from Windows (it is an app in the MS store). But yes, well worth a look see.
If you want support from Kodi.tv (and really that is where you should ask for support on this addon) first try the addon on a fresh install of kodi. You can install it as portable so you don't lose all your other addon. Once you have this addon on a clean Kodi install, if you are still having the same problem, you can now provide a clean log for them to look at and they will treat you like an upstanding member. Not so if you have 3rd party addon in your log when you provide it.
