Unable to subscribe to Realms Plus

Hello,

For the past several days I've been trying to subscribe to Realms Plus on Bedrock Edition for PC, and have been unable to do so. Every time I attempt to do so, I receive this notification 

"Your device lost connection to the store and we can't confirm this offer is still available. Please check your internet connection or try again later." I'll attach an image below to confirm. 

In terms of troubleshooting I've done just about everything. 

• I've reset my internet, 

• reset the WIFI in my PC, 

• reset Minecraft on several occasions,

• reset my PC on several occasions, 

• attempted to use a hotspot for internet connection, 

• used a separate PC with an ethernet connection, 

• insured my Xbox account was connected and I was properly signed in, 

• checked that the connection to the market place/servers were secure and functioning (they were), 

• disabled any and all possible applications that could be causing an issue (with both PCs)

For all intents and purposes this feature should be functioning, and any further tinkering or intervention is indicative of an issue with the product, not the user. I will also add that I know that I'm not the only person with this issue, as I've seen numerous complaints about this spanning several years with zero support or solution from Mojang (To my knowledge). 

Please notify me of a possible fix to this problem, or if you could fix the issue on your end. Thank you.
