Yeah, I don’t think I agree with that. The only servers you would have difficulty connecting to, are ones that don’t share the same version as you.
e.g If the Official Server 1516 has updated their server to the release from today, and your client hasn’t updated, you would not be able to connect to that server.
Likewise, if your client updated to the version today, and the Official Server 1516 had not yet applied the new update to it, your checksum would also be off, and you would have difficulty connecting to the server.
The only reason I say this is because I also have the Microsoft Store client, and so do you. There has been no update pushed to that. The Steam version however, did push the hotfix today.
