Prompt

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 details, so I can't confirm what's currently active on your subscription. That said, here's the general logic that usually applies: - If you upgraded to Pro in March and the subscription has been renewing/paying without interruption since then, your account should currently be on the Pro plan, which typically includes Pro-tier priority support. - Priority support is normally tied to an *active* Pro subscription, not to how long ago you up
I don't have any way to see your account or billing status, so I can't confirm what's currently active on it. A few things worth noting: - An upgrade in March would normally mean Pro benefits (including priority support, if that's part of the Pro tier) have been active since then—assuming the subscription hasn't lapsed, been downgraded, or hit a failed payment. - Whether "priority support" is specifically included depends on the provider's current plan definitions, which can change.

I don't have any way to look up your account or billing details, so I can't confirm what's currently active on your subscription.

That said, here's the general logic that usually applies:

- If you upgraded to Pro in March and the subscription has been renewing/paying without interruption since then, your account should currently be on the Pro plan, which typically includes Pro-tier priority support.
- Priority support is normally tied to an *active* Pro subscription, not to how long ago you upgraded. So the thing to verify is that the plan is still active and hasn't lapsed, downgraded, or failed a payment.

To check for certain:
1. Open your account/billing settings and look at the "Current plan" or "Subscription" section — it should say "Pro" with an active status and a next renewal date.
2. Check that your most recent invoice was paid successfully.
3. If it shows Pro as active, priority support is included; you can usually access it via a dedicated "Priority" or "Pro" support channel or by emailing the support address with your account.

If the dashboard shows anything other than an active Pro plan, contact billing/support directly with your account email to sort it out.

I don't have any way to see your account or billing status, so I can't confirm what's currently active on it.

A few things worth noting:
- An upgrade in March would normally mean Pro benefits (including priority support, if that's part of the Pro tier) have been active since then—assuming the subscription hasn't lapsed, been downgraded, or hit a failed payment.
- Whether "priority support" is specifically included depends on the provider's current plan definitions, which can change.

To get a definitive answer, check the billing or subscription page of the service in question (usually under Account → Plan/Billing), where it should show your active tier and its features. If it's unclear there, contacting the provider's support with your account email ([redacted-email]) is the reliable route.
