I have just upgraded my old FireTV box with the new FireTV Cube (model A78V3N) and have hit a problem with text entry for searching. Importantly I use a Harmony Ultimate remote to control everything rather than the standard Amazon remote.
So I click the blue search "magnifying glass" and a one-line input box appears saying "Search text (select for keyboard)" but when I click the OK/Select button (on the Harmony) it appears to generate a carriage return (see several blank lines in attached photo) instead of the normal soft-keyboard popping up on screen. Clicking OK again generates more blank lines and then an error pops up on screen "VolleyError com.android.volley.ServerError:" (I am guessing that the error is because Emby server cannot handle line breaks and so isn't really relevant but include it just in case.)
Everything else within Emby seems to work fine and everything works fine with Amazon Video, Netflix and Plex text search, it seems to be just Emby text entry affected - does anyone have any ideas how to fix this?
