Pics uploaded with 360° one shot camera loss resolution

I saved the pics using Lightroom mobile at ipad platform.
NO EDITION.

I used Adobe web in order to save space due to I was out for vacations and all the pics were saved on the cloud. When I returned home and downloaded the original files from the Adobe Lightroom cloud, the resolution was reduced.

360 One shot camera used= Samsung Gear 360 first generation.

Pics were not stitched. Were uploaded with the 2 spheares on each side

Pics were uploaded at max resolution of 7776 x 3888

.

Days before when I tried to dowload them, they were at 2262 x 1131 STILL AT WEB... before downloading them !!

Thanks
