This dreaded problem, that I've reported in the past, has again made its way back into Affinity Photo 1.9 after being absent for the past year or two. Every now and again Affinity Photo 1.9 won't let me save my documents, thus losing work and redoing everything from scratch. Please check the screenshots below. These are only a couple of instances among several that this have occurred to me since I installed 1.9 a few days ago.
