@ MissCheetah lets say i hate the ps5 version, due to its limited functions, if i purchase PC version of the game. Would i be able to log into pc with my current battle.net and still have all the progress i havw already completed from ps5 on to the PC?? If so that means i just need to buy a copy of the game and does that apply to any kther platform as well??
Yes, cross progress means that you can buy the game on any platform you want and keep your progress.
This assumes that your PS5 was properly linked to your Battlenet account of course. That is where your progress is kept.
Some people have had issues due to account linking errors, so feel free to read this first.
