When I open Agenda on iPhone…

… … this screen appears. It is not possible to search, create new notes, etc.

Everything is arranged by opening one of the two side parts

Agenda latest version of sw. iPhone 14 Pro Plus

We’re indeed aware of this glitch, we’ll do our best to fix it in the next update. In the mean time, rotating the phone to landscape and back, or opening the sidebars, editing of the note etc will usually fix the issue.
