Error when attempting to upgrade to Pro

I’m currently on the Starter Plan and am attempting to upgrade to Pro, but receive the following error message:
unable to update subscription: {:code=>53500020, :message=>"This action could not be performed, because you are trying to amend an cancelled subscription."}
I’ve been a Netlify user for a long time and once used a legacy paid plan - could this be the cause of the error?
Advice appreciated - thanks!

Hi, @tombennet, I’m guessing that is the issue as well. Do you want your team changed to the new Pro plan? If so, I’ll make sure we get that done for you.

We’re sending you an email about this and we’ll follow-up with you there. Please do reply here if you do not receive that email soon.

I have this error too and it’s of importance I can update my account asap.

Hi, @reimertz. and thank you for getting in touch.
