In the German user manual, it was written that a mouse is also required for the Netflix app in order to navigate.

We connected the beamer with a Bluetooth mouse. Awkward, but at least it worked.

(Yes, I know. At the beginning, it actually worked quite well for me with the remote control in the Netflix app. However, it often happens that the button presses sometimes (avoidably?) show no reaction, then again they do. The following seems to be operable only with the mouse: switching profiles, operating the settings menu, changing languages. Can only be operated awkwardly/indirectly: Reaching the search function, pause/start. So it is best to search/set/prepare everything in the corresponding profile on the PC and then only select to start on the projector).

Which Bluetooth mouse can you recommend for operation?
