Phones show a different crop
Facebook's cover photo is 851×315 pixels, about 2.7:1. Computers show it at roughly 820×312, but phones show it closer to 640×360, which cuts off the left and right sides.
Keep text and faces in the centre so they survive both crops. Facebook recommends an sRGB JPG under 100 KB for the fastest load, so try a quality around 70 to 80 if the file is bigger.
The image is cropped from the centre to the cover shape, then sized to 851×315.
