I can confirm this being a bug:
- When filtering on all tags: broken, update 30-06: it works!
- When filtering on recommended: broken, update 30-06: not able to test
- When filtering on favorite tags: it works!
- When filtering on custom tags: broken, update 30-06: it works!
Also look herehere for a case that supports this being a bug, it is marked completed, but that can't be confirmed yet by community members.
To me this is an important feature. If it isn't implemented in the new navigation, I would rather keep the old one.
