Recover photos from lighteroom when phone is reset

[#1]

Dear

My iphone is reseted and I had to reinstall the Lighroom app. When I logged in and checked, all edited photos were gone ( at that time I still used the previous version - trial ). I would like to ask if there is any way to recover all my photos from lighroom's acount. I haven't synced to anywhere. 

Thank you

I've moved this from the poorly named Community Help forum (which is the forum for issues using the forums) to the Lightroom Mobile forum so that proper help can be offered.

Unless you have a back up of the whole device then unfortunately not.
