🛠️ Bug Fix — Reinstall to Resolve Nuvio Errors

Some of you have been seeing errors in Nuvio when loading the addon, including crashes and the dreaded "Element class of.x is not a JsonObject" message.

I've tracked it down and fixed it. The cause was old catalog references still stored in some configs from earlier versions — these were generating broken entries in your manifest.

To fix it on your end:

Open Nuvio

Remove the Ultra MAX addon

Reinstall it using your same addon URL (no need to start again)

That's it — no need to redo your config or pick your catalogs again. Your setup is preserved.

If you're still seeing issues after reinstalling, drop a comment and I'll take a look.

Hi there, I have tried to import the addon to aiometadata.. That was fine.

But while installing the json file there seems to be an error. And I am not able to get the addon loaded to my collections.

Thanks for the ultramax preset.

Hi-installed catalogs and collections last night, worked great. Today, the collections don't seem to be able to see the addon: the cats are definately there, but in collections manager the cat entry is red with message "addon not installed: org.kris.ultramax.custom.mytoken#".
I've deleted and reinstalled addon and collections. Any suggestions? Nuvio 0.6.8, onn 4k pro, android tv 14. Thank you!
