Do you not get a 4G type connection anywhere you go ?
Trying elsewhere away from the masts your currently latched to helps to rule out your local masts at issue. Mast congestion can play a part too where lots of people are accessing the same masts.
Try a soft reboot by turning your phone Off and On.
Also try connecting to another network in your phone's connection settings and then re choose Vodafone.
Vodafone have a help thread here with an included template here … Network-issues-initial-checks-and-template.
You can ask customer services via Live Chat or 191 or the Vodafone Social Media Team's via Contact-us-for-account-specific-queries to check your account to ensure 4G is still provisioned on your account after the upgrade.
If you perform a forum search you'll see that some people have had to contact customer services to get 4G turned On.
Also you could ask them to reset your account to try and kick start 4G.
Sometimes trying your your sim card in another phone can help rule out the phone at issue or the sim card.
Check 4G is selected still in your phone's connection settings..
