Autocomplete mentions

the bug i noticed was in touch mode autocompleting usernames when trying to mention someone doest work but it works fine on normal mode. this is on the same thing on all devices.
is there a fix coming for this

The fact that you can’t mention someone in mobile mode is a known and long-standing feature request, yes.

I don’t think a fix for this is coming soon - especially since the current “mobile” version is kinda considered deprecated and will probably be replaced by a new thing at some point in the future.
