@amanda643 and @Anatole I've tried to join my realm in my mobile version of bedrock just once, same account, then disconnected. When i tried to joined again with N-switch i was able to join my realm. Hope it helps.
Same here. Switch bedrock update to 1.19 and i am not able to access my realm. Have also done the same as amanda643 same results. Still can't access my realm.
