Adding support for Live Photos (Image+ the short video files) would be really appreciated.
At the moment, only the static image is backed up. The live photos are now supported by most Androids as well. They contain memories and moments which sometimes are better than the photo itself.
This is support by Google, OneDrive, JottaCloud, Proton...
Mega at the moment backs up the video files but shows them separate, which is bad and your gallery becomes a mess.
They've promissed to add transparent merging 3 years ago, but never happened.
