Photoshop is crashing a lot on the ipad, losing hours worth of work.

This has been happening for about a year now, where I’ve noticed that Photoshop on the Ipad crashes randomly and loses some amount of your work. Yesterday it lost 2 hours worth of work. I have continually checked the space on my Ipad, which there is plenty of, so I don’t think it’s due to my Ipad’s dada load. This was not happening in years past, it’s just within the past year.
