Program Slow does not load in Safari

This new version of adobe express is awful. It worked beautifully when I was allowed to use Firefox, but since your update last month, this program takes forever to load, seems like I am back in the early 2000's with dial up internet. this is not an internet connection issue either. this is all specific to this new version of adobe express. The program will glitch out & I will lose all work that I have worked on, it does not load appropriately, this new version is garbage for anyone trying to create anything for their business, work, or school projects.
