Not sure how it has to work. This is not a big issue, but i have bookmarked a room and waited for long for bookmarks menu to appear (as it’'s said in SPARK-519). But it only appeared after relogin (though i had to wait for a few secs still, next time i relogin it was here at once (saved in settings probably, or cached?)). But maybe something could be done to make it appear when first bookmark is added.
to test this, you have to have no bookmarks at first
