403 Realm Not Invited

[rustywolf021]

I've been playing on my friends realm for a while now, and ever since the Microsoft account thing I have not been able to log back into that account and join though Aristois. I will log into my donor account then log into my other account in the client then when I try join the realm it says "403 Not Invited" even though both my accounts are invited to the realm and I can join them on normal Minecraft.

You cannot join a realm while using an alt manager, it will invalidate your session and prevent you from joining. This has always been the case
