Can't log in weight

Half10500 on

Thailand

When I log in weight, it show no data. When I click to see previous data it say I have to log in weight(which I did a second ago.) I have this problem since last year and contact all the customer support and they gave me no resolution. I already delete and reinstall the app, restart the iPhone, nothing change! The app is good but the performance is so poor. Even though the fast record itself it still could not graph itself out like in 2022 December. I subscribe it for something, but not something like this. So 1 star until improvement.
