The support doesn't exist. There download app is non functioning and support is non-responsive.
I paid before but the app was always buggy so I went back to free. Honestly Google drive offers basically the same free space always work and syncs as it should.
A few years ago MEGA was the best.
No doubt they are losing money and no longer updating their software. Since its not working.
Shame there is no support wonder if they realize the files downloaded are corrupt.
