iPad版LR无法恢复照片

Hello, I am a Chinese user of adobe. When I was using Lr for iPad, I encountered the situation that deleted photos could not be recovered. Every time I click to recover photos, I will only be prompted to restore photos. mb cloud storage space Your space is insufficient and can not be restored, but my iPad memory and iCloud storage space are sufficient. I have used various methods, but there is no way to contact me in China, nor can I find the adobe official way to contact me in addition to social accounts. Is there any way to solve my problem.
