Discourse 3.5.0.beta8-dev (79ff804509).
Apple iPhone 16 Pro, iOS 8.5, Safari.
Apple iPad Air 13, iPadOS 18.5, Safari.
I am unable to select the @username I want to mention when using iOS because the list of names disappears off the top of the screen.
This is compounded by the fact that Discourse is sooooo good at ordering the list of names with the name I want always being at the top, and therefore inaccessible 
Here’s how it looks on iPad:
And the same on iOS:
We’re working on an overhaul of the ‘autocomplete’ system right now, so I’ll make sure we test that this problem is resolved as part of that. Thanks @Richie
Just to link them up:
This should be resolved in the latest version of Discourse - the autocomplete menu now opens based on whether the top segment or bottom segment of the screen from the cursor (if you imagine the cursor as a horizontal line dividing across your screen) has more space. So for the cases pictured here, you should expect it to appear below the cursor.
