HNT helium wallet no value

Hi there,

I’m having issues with my Helium wallet.

I’ve have been completely put off by the whole mining thing and recently saw that HNT has moved on to (saw Vosk new video! Thanks).

I can see some HNT and IOT in my wallet but below that it has a $0 value.
I also tried to transfer it to and failed.

Could someone please guide me on how to get these working? Why do I have $0 value on all my HNT and IOT.
