Picture of Discover not showing what needs updated, while Get-New icons shows things that can be updated. With a bit of the terminal ouput thats posted below.

***
In  both nixos and arch on the latest stable kde builds Discover won't update plasma addons. 
***

SUMMARY
In discover it will let you download addons just fine but will never ask you to update them to do so you have to go to the Get New section of there that icon or theme is from. That fails sometimes as well lately but that needs its own bug report. 

In terminal when opening discover for the first time it shows its looking an sees the addons. 

STEPS TO REPRODUCE
1. Install some icons or theme parts with git new.
2. See that one needs a update (Ars-Dark-Icons are updated often)
3. Open discover an check for updates by refreshing the list.

OBSERVED RESULT
Nothing to be updated other then maybe flatpaks that day. 

EXPECTED RESULT
Show addons to be updated. (Same thing happens when you install a addon directly from discover.)
