Since an Update of the Prime Video App a few days ago, the Prime Video App doesn't do Content- and Framerate Switchting anymore. A few weeks ago I watched the last season of "The Expanse" and the app correctly switch my my default settings 4K SDR 50HZ to 24Hz HDR when I watched "The Expanse". Since an App-Update a few days ago, that switchting doesn't happen anymore. Video stays stuck at 50Hz and HDR isn't switched on automatically. So annoying...
