Hi!

I have recently purchased Minecraft on iPad, running iPadOS 13.4, but I am unable to play online due to problems connecting to Microsoft Account in game.
I am trying to setup so that me, my daughter and some of her friends can play together online.
Have checked previous issues on same topic but no luck resolving it. BDS-1305 BDS-3739 MCPE-66289
 
Problem Description
 
I am unable to play on online servers or connect to any minecraft realms.
I seem to be able to log into my Microsoft account in the game, or at least my GamerTag shows, but when trying to connect to a server I get the error message:

"You need to authenticate to Microsoft services".

Minecraft Realms are no able to load either with the error message:

"We could not connect to Realms right now. We will try again soon"

 So I am able to play offline and on LAN but not online due to the errors above.
Microsoft account that I use runs without any restrictions (no children block of online play or similar)

What I have tried

#1 I have confirmed that I can login to the Microsoft account with the Xbox app on the iPad so the credentials are valid.

#2 I have made sure made that date/time are aligned with the server/clients 
#3 I have tried switching to a secondary Microsoft account but with the same erroneous result.
 
#4 I can login to the online servers from my Windows machine that runs on same home network and my network connection is otherwise stable.

#5 UPnP is enabled on router and I anyway opened xbox live ports on router specifically (even though it should not be needed as I can login over the xbox live app), but same error.

•Port 88 (UDP)

•Port 3074 (UDP and TCP)

•Port 500 (UDP)

•Port 3544 (UDP)

•Port 4500 (UDP) 

#6 Started hosting an online server with exact version as the IPadOS bedrock version, but same error.  

 
Additional System Info
iPad 10.2 7thGen 

I would really appreciate some support in order to get this working.
I am happy to provide additional information on request.

Thanks in advance
Anders
