New Charge 6 won’t set up

[fifinaif]

I had my new Charge 6 arrive yesterday. I started to set it up, charged it, downloaded the app, did everything it said. It synced to my app fine but when I tried to update it couldn’t do it. It says it’s connected but it just keeps buffering and no progress bar appears on anything. It then says it wasn’t able to update, try again. I’ve gone through other posts and tried multiple other things, pressed the button on the charger, uninstalled and reinstalled the app, uninstalled the Fitbit from the app, restarted my phone, you name it, I’ve tried it. The Fitbit just keeps alternating between saying to download the app, a picture of a phone with a download symbol in it or the time. I don’t know what else to do other than return it and give up on a Fitbit. Any help would be greatly received
