I think so
When composing a new post (creating a new topic, or replaying) the buttons on the toolbar doesn't respond (only the last two of them, the question mark and the poll).
Furthermore the tag icon is shown instead the smiley icon that is shown on PC layout.

I checked the behaviour of the buttons in PC and it is ok.
I confirm it, I tested on Chrome and Firefox for android.
file as bug in issue tracker please.
