Hey, seems I also ran into some probs.
There are for sure some patches updated, but warehouse do not shoe anything in updates (queue empty) but at least 'search engines for sfos' can be upgraded in warehouse.
I do not want to check manually for each installed package. So what can I do?

pkcon refresh && pkcon update

Problem solved with this command.. nothing wrong with btrfs. just needed a refresh ... thnx mate..

Same.
Update did not bring any new package to be updated.
Also checked for updates in warehouse once more.
And still no update available. But situation with 'search engines' is still the same

show me where is the problem then

@coderus
see above screenshots.
No updates available in warehouse nor via pkcon update but mentioned package is installed in older version.
( and I am afraid there could be more, as patches got updated for new sfos version)

no updates means no updates. it's not a problem if there are no updates. so, then there is no problem?

Either we speak different language (for sure ) or we both do not get the other.
Of course if there is no newer version then there is no update.
But having a look at the second screenshot shows:
installed 0.0.7
available 0.0.8

And that is something I would expect warehouse or pkcon to detect on their own. And not by checking each package manually.
Or am I completely blind?

installed - available checked by openrepos api, not repos. if you have no updates in profile page or can't install/upgrade reapply repos via ssu script.

Didn't follow all the discussion about Warehouse and updates, but there is definitely an issue in this area. When you tap on "Check updates", there is nothing, and you have to swipe back (to the left) and forward (to the right) to see the updates available.
