Receiving Samsung account changed and can't add July challenge month.

Receiving Samsung account changed when attempting to join new monthly health challenge. I'm unable to add the new month to enter the challenge. Also, I can't select the old month either. Nothing happens when I select the old month.

I'm having the same issue.

I un-installed and reinstalled Samsung Health. That seemed to fix the issue for me.
