There was a big update recently, perhaps you need to update the app?

Probably all you have to do is force refresh the repos. I can't tell you the exact way to do it, but it's pretty straight forward. If you can't figure it out by yourself just google something like "kodi force refresh repo" and you should find plenty of guides.

Are you talking through the Fusion Add-on app? If you did Fusion and installed the "begin here" repo/zip, than I assume that is what you mean.

A few days ago some categories where empty, and yesterday all categories were empty. The only way I know around it is to go into where you installed Fusion but go into the repos, there are 3 categories, choose English (or XXX if you prefer... :P) and install what you want from there. It can be a guess though. For example, Exodus is named but Phenix is not named by itself and is within a different name (sorry, I forget which name). If it is cCloud, I believe that is under something like Podgod (forget the exact name).

As for the update, SPMC hasn't gotten an update as of yesterday (haven't looked today or used SPMC today). Since it is a fork, it makes since that it will be updated a little later than Kodi.

After the update i had a few issues with kodi. This workt for me :

1.factory reset 2.connect my peripheral 3.shut down and wait a few moments than start 4.install kodi from the play store, until now no issues for me
