@EduMerco It could one of (at least) two issues:
- a bug in how unseen notifications are counted
- we've set notifications (as well as messages) to automatically be marked as seen using https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API to do so only when they come into view (i.e when scrolling) and seems that's not getting triggered if you don't scroll. Needs more research...
