v31 - Can not remove pictures from favorites (heart symbol) [Fixed]

[masterjp]

With v31 I tried to remove pictures in my favorites folder.
The heart symbol does not work.

in view mode, you click on heart icon, and nothing happened even after a 'pull to refresh' in browser?

I found the cause of the problem.
The image files in my XnView favorites were created by the Samsung Gallery app.

XnView Gallery shows me the Samsung Gallery app favorites,
but it can’t delete them! That’s why I was having trouble removing them.

This is always a bit confusing, because I’ve already created different favorites in both programs and can’t always tell which program was used to mark them.

It seems that there is currently no way to resolve or change the fact that Samsung Favorites cannot be deleted.
