Can't load Realm... out of date server

When I updated my iPad to 1.16.200 I can not load Realm. Error reads:

 

Cannot connect! Outdated server

 

The realm you are connecting to access is of a different version.

Contact the owner of the realm to address this issue.

 

owner logs on fine. He uses Minecraft on a Windows PC. I have checked my client it is version 1.16.200. Please help
