Have the same issue, email from Netflix yesterday to quote;
"Unfortunately, Virgin Media has let us know that your account could not be billed through your Virgin Media subscription. We are cancelling your membership, effective from Monday, 25th April 2022

Obviously we'd love to have you back. All you have to do is restart your membership."
Netflix askes me to restart membership when i access through the my TV box or phone app etc.
Have check My VM as you have suggested and there is no Netflix option showing as per your screen shot.
Netflix does appear as an "On Demand" item on my latest bill though.
As far as i know i have made no changed to my Netflix subscription.
Hopefully this information helps.
