Newbie blogger: Add a video of your own

Tried the blogger way and yes, i can embed my own video from google photo backup but it won't play at all no matter what i do.

steps below don't work =(

When you do the above & select 'from your phone' this is what you get.

After playing around, i found the only way this method will work is to:

a) upload the video to youtube as host, set to public

b) Embed it like normally how we embed youtube video. Share , get the url or copy the blogger code to Html.

Selecting from 'my youtube' then it should work.

Finally able to fix the last post about my first Sogo member sales day trip , published without knowing that all the videos are not working.

Cheers~
