I’m getting an error: The data couldn't be read because it is missing.

I have checked Libre 4 and LibreLinkUp. I have checked my username and password.

I should work. It used to work.

Me too. For days now.

Same here, logging in and out of Libre LinkUp and/or restarting the apps involved doesn't change the problem.

There's a new end user agreement and privacy policy seemingly preventing the data from being sent, but the LibreLinkUp app isn't immediately prompting you to view it. Try to sign out within the LibreLinkUp app and sign back in. It likely will show the new end user agreement, which if accepted should get the data flowing again.

That did the trick.
