Let me start by saying I have already checked your entire faq page and none of that had any solutions; I already tried a bunch of stuff on my own.

I regretfully own your faulty software on Android, Sony Playstation, Microsoft Windows and Microsoft Xbox; they are all linked to the same Microsoft account.

I was able to use realms just fine at first; it wasn't until I purchased a second realm that I began to experience all kinds of issues.

This is an issue with REALMS not Singleplayer and not connectivity as I can play multiplayer and access the store just fine.

I have cleared the cache on Android, I even uninstalled and reinstalled on Android, playstation and windows. I checked for app updates, driver updates and platform updates... everything is up to date. I have signed out o my Microsoft account on each device and resigned it. I waited and tried again later. This issue has gone on for over a week now and I even contacted the help email. You were completely unhelpful and basically just wasted my time. 

I can load into the realm on Android, Microsoft Windows and Microsoft Xbox. My playstation (my preferred console)cannot load the realm. My realm is a new world with only three players so far. So it not that large in size. I can play the realm on the devices that load without much issue. However again, it will not load at all on playstation and Even more so a problem and frustrating is that I CANNOT BACKUP/DOWNLOAD ANY OF MY REALMS OR THEIR CLOUD BACKUPS. I CANNOT DOWNLOAD REALMS TO ANY DEVICE. All of my devices have more than ample room to download this world 10+ times over.

ANDROID

PLAYSTATION

WINDOWS

XBOX

I have seen support tickets for similar issues since 2017,some which you say is resolved when those people said you never resolved it and yet here I am also with this issue 4 years later. I will wait one additional week for a response here; otherwise I am just going to demand a refund for all my copies of Minecraft and your realm subscription and ask that you revoke my licenses because I have no desire to pay for and support a faulty software that does not function as intended, promised or advertised. I cannot enjoy my game or the time spent on it as you fail to address dire performance issues from several years ago. It shows you have made no good faith effort towards your customers/users.

Again I have checked this bug form and FAQs as well as emailed help...none of the posted solutions have worked or resolved this issue. It is on your end. If you can't fix it directly in game at last allow users an alternative way to download and backup their realms because this is fucking ridiculous especially when you trying authorizing subscription charges ahead of the scheduled date for a service that doesn't even work properly. 

I didn't buy my realms or any of those copies of Minecraft to risk losing hours of gameplay not just from me but the other three users as well.
