I have a charge on my account for Netlify Basic site yearly charge $90/year. Yet the pricing on the website indicates Free for starter accounts and I’m not sure where this charge comes into play.
Sounds like you’re on one of our super legacy plans! This particular one came with a few extra niceties. Nowadays, I believe the two features which are on this account and not on our regular Starter are proxying and password protection. Given this, most folk would be more than safe to revert to Starter and feel no pain .
