Yes, the app lets you download up to 4 versions previous, but the last version that worked flawlessly was 20.0.9. The issue I am having is that my document with hundreds of layers and a HUGE pixel dimension won;t save at all, won't export or anything. It worked in the above version flawlessly. The newer versions for some reason don;t like the large files sizes and amount of layers. It gives me an error anytime I try and save but the error message doesn;t give any information "Could not complete your request mebace of a program error"
