Version 1.14 will not install on Windows 10

I currently have version 1.13.1 installed but it won't update to version 1.14, which means I can't create shared games with my children. I have tried resetting Minecraft in Settings > App, tried resetting Microsoft Store in the same way, and finally tried uninstalling and reinstalling Minecraft. Every attempt just installs v1.13.1.

Please could you advise how I can get this upgraded?

Thanks

Ned
