Is anyone having trouble refilling their HCQ script? From Walmart in particular.

I sent in a refill request through the app. Normally, it takes a day, maybe two to get refilled. I sent the request two days ago, and now they estimate it will be another week? Is there a shortage again (please no), or is it more likely a problem with this specific Walmart? I can call them tomorrow, but they're closed now. Just wanted to know if it's happened to anyone else.
