Charge 2 not showing but still paired to old phone

[PriscillaRP]

I got a new Fitbit Versa and gave my old Charge 2 to my mum.

I paired my new one fine with my phone and unpaired the old one. The Charge 2 is not showing on my phone but I cannot pair it to my mum's phone because it's unable to find the device.

If I try to pair to my phone, it finds the Charge 2 and shows the code necessary to pair it.

I've moved all devices away, turned bluetooth off and on again but it still didn't work.

Thanks for your help.

When you say you unpaired your Charge 2 from your phone, do you mean from the fitbit app? If so, did you also go into the phone's bluetooth settings and "forget" the link to the fitbit? If there is still a bluetooth connection then it can block connection to another phone.

Yes, I've unpaired from the app and "forgot" the bluetooth connection. 

After a few turning off and on again, it seems to have worked.

Thanks for your help.
