Today I noticed problem with Warehouse and Jolla store. Jolla store initially stated that I have no apps installed.
Ok, I looked for solution and found following solution:

from here: https://together.jolla.com/question/...?comment=38451

After these commands Jolla store started working again. And I saw my apps and could download new ones.

However, Warehouse still gives error: "/repodata/repomd.xml not found on medium". Screenshot:


I also tried "pkcon refresh" and "zypper clean -a" commands, however, with no luck. Screenshot:


Any suggestions?

Problem was solved after latest OS update.
