Minecraft version crossplay?

Soo… last Week, Minecraft on xbox updated to Minecraft 1.11.2. I play on the Switch, and it is still on Minecraft 1.11.1.

I am unable to play crossplay Minecraft on my switch with my buddy on xbox because we have different versions.

I submitted this question to Mojang support, but they are still working on emails from March.

What should I do?
