Fitbit Versa Lite won’t set up/update

[cmpamcgi]

Hi, would anyone have any advice or knowledge. My Fitbit versa lite is refusing to set up. The watch has been detected on my app on my iPhone but has not recognised to the watch that it’s on a device. I keep getting the ‘to start download the app’. The things I have done so far is deleted and reinstalled the app several times as well as deleting the watch on and off the app. The watch allows me to set up until it does the update which took 2 days to get the blue line across but never have I got the watch screen. I have had an issue with this for a week now!!! Any ideas on what is wrong
