LibreLink Up does not collect data

Hello good,

I don't know if I will be only me but you are not taking the data of the FreeLink Up app.I changed from a pixel to a Samsung who according to everyone is the best for Freestyle but it doesn't work well for me and the Galaxy Watch stays in blue for a long time.

I don't know if it was to change my move or I will have to wait for a new sensor to do well

What Samsung mobile model is it?

It is weird that FreeLinkup work, the only time I have read it was because they needed to update it.
