The registry nameservers correctly list your new provider as authoritative on your domain:
$ dig helloorbital.com @a.gtld-servers.net NS
; <<>> DiG 9.11.5-P1-1ubuntu2.5-Ubuntu <<>> helloorbital.com @a.gtld-servers.net NS

You now just have to wait. There is no "propagation" even if people say so continuously. If you did just query for your name before the switch you "polluted" your recursive resolver cache with the old nameserver information, for a TTL of 172800 seconds, that is 48 hours.
Anyone else not having queried for your domain name will see "immediately" the new nameservers after the switch.
Three major public DNS services already have the correct updated information:
$ dig helloorbital.com @1.1.1.1 NS +short
ns-939.awsdns-53.net.
ns-1216.awsdns-24.org.
ns-1864.awsdns-41.co.uk.
ns-262.awsdns-32.com.
$ dig helloorbital.com @8.8.8.8 NS +short
ns-1216.awsdns-24.org.
ns-1864.awsdns-41.co.uk.
ns-262.awsdns-32.com.
ns-939.awsdns-53.net.
$ dig helloorbital.com @9.9.9.9 NS +short
ns-1864.awsdns-41.co.uk.
ns-262.awsdns-32.com.
ns-939.awsdns-53.net.
ns-1216.awsdns-24.org.
So there is no real question there to answer, you were just not understanding how the DNS works and how changes appear worldwide.
