Health mate error while setting goals

Dear support,

My Health mate app keeps asking me to set goals (although I already did through the web app). However, when I click "tap to read" about setting my goals and then press the button "Set my goals" It asks me to select a user while telling me "no user" and returning an "Internal error. Please try again"

I've tried multiple times on multiple days now, however it keeps returning this error.

Is there any solution for this?
