I was on the Free plan last year, but I upgraded to the Pro plan back in March. Does my account currently include Pro-tier priority support?

I don't have any way to look up your account or billing status, so I can't confirm what's currently active on it. A couple of things worth checking, though: - **Whether the upgrade actually went through and is still active.** A March upgrade would normally still be in effect now unless a payment failed, the plan was cancelled, or it was a time-limited promo. Your account's billing or subscription page should show the current plan and renewal date. - **Whether priority support is actually a Pro
I don't have a way to look up your account's billing status or support tier, so I can't confirm what's currently active on it. That said, if you upgraded to Pro in March and the subscription has stayed active (payments going through, no downgrade or cancellation), Pro-tier priority support would normally be included as part of that plan. The thing to verify is simply that the Pro subscription is still current. You can check quickly by: - Opening your account's Billing or Subscription settings

A couple of things worth checking, though:

- **Whether the upgrade actually went through and is still active.** A March upgrade would normally still be in effect now unless a payment failed, the plan was cancelled, or it was a time-limited promo. Your account's billing or subscription page should show the current plan and renewal date.
- **Whether priority support is actually a Pro benefit.** This varies by product. Check the plan's feature list or pricing page for the specific "Pro" tier.

If both check out, then yes—an active Pro plan would include whatever support tier Pro covers. If you tell me which product/service this is, I can help you find the right page or draft a message to their support team.

You can check quickly by:
- Opening your account's Billing or Subscription settings page, which should show the active plan and renewal date
- Looking for a recent invoice or renewal receipt in your email ([redacted-email])
- Contacting support directly and asking them to confirm the tier on file

If the Billing page still says "Pro," you're covered.
