MyCloud Android App Crashed when try to play video

Hi, I recently purchased a PR2100. when i install the app on my LD G6 and try to play video, the app crashed and closed. i have tried reboot and reinstall, it still the same. the error message is the following:

//////
unfortunately, my cloud has stopped
//////////

i can access photos fine but just not the video i have on the PR2100. i can use plex to access the video as well. Does anyone experience similar issue?

thanks
