Attempted again today (June 28) on PS4 after installing 1.21.92. Second player still signing in as a guest of first player.
Tested further, second player has access to their microsoft account end chest, but they do not have their equipment or pockets inventory the exit the game with when playing solo.
We noticed on 6/17 after the update this issue occurred on both PS4 and PS5 as well. Just tested again and still seeing the issue.
New, maybe related, issue - one of my kids was playing solo in the realm when we experienced a power outage today. Now when she logs in the realm, it’s not her microsoft account character, but a new character with no items. It seems like her playstation account is overriding the microsoft account. Every other account on the playstation can log in fine when playing solo in the realm.
Same is happening on PS4 and PS5. We were using realms though and I opened a ticket. I didn’t see this ticket due to being on the realms filter.
Just tested on PS5, same issue. PS5 system software: 25.04-11.40.00.05-00.00.00.0.1
Still experiencing issue on PS4 in version 1.21.93
