I got on Minecraft tonight intending to play online with my brother.  When I log in, I see him in my friend list, but when I try to join his world I get an error that says "Could not connect: Outdated client!".  I updated Minecraft earlier today, and it shows I am on version 1.21.2 (using Windows 11, Bedrock edition).  My brother checked his version, and it is also 1.21.2 (he's on Android, Bedrock edition).  We have both checked and double checked our versions, made sure we've updated and installed all current patches, restarted our devises, logged out and back into our Microsoft accounts, tried connecting to different wifi connections...but I continue to get the error message that I cannot connect due to "outdated client".  The clients do not appear to be outdated.  I don't know what else to troubleshoot or try.

This is the first time we've had trouble joining each other's worlds.  It appears to be a bug with the new update.
