So I have 2 distinct account a MR 10 Founder account i've decided to let go when my PC broke down 8 years ago and a MR 30 Xbox account with thousands of hours invested in... My xbox one is old and just doesn't keep up with the graphic anymore and I want to move back to PC. What will happen to my founder status if I decide to make my Xbox account into my primary and merge my founder account as secondary ? Will I lose the founder status ? Will it carry over along Excal prime and co. ? They say Excal prime and Co. Are locked to PC but I shouldnt worry about it since now i'll play with my PC right ? It should only be locked if for whatever reason i decide to boot my xbox and play on this console instead ? Am I getting this right ?
