So, I bought Destiny 2 for PS4 and PC, and am deciding to move to PC. If I cross save, and move my PS4 Destiny 2 account to PC, will I still receive the Universal Hero emblem on my PS4 account? I have it already on my PC Destiny 2 account; I was just wondering if I decided to active cross play and use my PS4 account as my primary account, will I still have the Universal Hero emblem on there?
What you are describing here is called account merging, and that is a service that Bungie is not providing with Cross Save. The characters that you select as your primary set when you enable Cross Save will have the same gear, emblems and triumphs on every platform you log into. If you select your PS4 characters as your primary and log into your PC, you will not get the emblems that your PC characters have unlocked.
