Question: Premium Access Pay by Check Timing

I fully understand how busy the Support Team/Mods are, and appreciate all the hard work!

I do have a follow-up question on the premium access process:
I received instruction on how to send in a check, which I just did. The instructions indicated to respond to the subs email address when the payment was sent. I sent a reply (with screenshot showing the initiated check), but what I wasn't clear on is: Does Premium Access get granted at that point, with a caveat on the payment fully clearing? Or only after the check has cleared?

Would I just reply back to that email to inquire on the status of my account if the check clears, but I haven't been upgraded?

Again, I'm more than willing to be patient, just want to make sure I don't inundate Support emails unnecessarily

Thanks again guys!
