Mid-split availability - auto upgrade?

Hello folks!

I can see that my area has had the mid-split upgrade (2000mbps is available with an increased upload speed at my address), but it doesn’t appear that I’ve gotten the upgraded speeds. I’m capped at the same 30-40mbps upload (gigabit plan 1200/40).

I do already have an XB8, if that’s of any help.

I’ve tried power cycling my modem to no avail - I’ve seen discussions mentioning an updated boot file?

Thank you!
