Opening the inbox automatically brings up “mentions,” but if you want to see private messages, you can click at the top and choose “all messages.” Clicking any of those options though will crash the app. You can still access those options through the side window, just not the dropdown at the top while viewing the inbox.
I’ve had this problem since Sept, and there’s a GitHub issue reported, if you want to add to it.
The bottom Nav inbox is the only one that seems to work right. Same with the inbox reply badge (telling you how many msgs are in your inbox.)
Issue #446

Edit to add: it happens for me with left drawer nav and the one in the More Actions area of the top. Only Bottom Nav inbox works right for me
