Solar charging not working

Every once in a while the solar charging stops working. When I restart the watch, it works again for a while.

Here is a video showing it:

Since then I noticed 2 updates in the last few days, was wondering if that is a known bug that was fixed in the latest release. Where can I find the release notes of latest 11.26 firmware?

  • This update seems to only concern Asian models and being in Europe, we therefore do not have this version.
    
    The contents of the release are as follows:
