I signed up for BCBSIL MedicareRx. How do I see Rx claims? Blue Access or MyPrime????

I signed up for MedicareRx Choice, received my card and created a BlueAccess for Members account. Walgreens filled an Rx for me  yesterday (1/2/2024). When I click claims button today in my BlueAccess  account, no claims found. How long does it take for the claim to appear after the pharmacy filled an Rx??

I called the Customer service at tel:1-888-285-2249. They told me I have to sign into MyPrime.com to see claims. Is that right?  What’s my BlueAccess account for and why does it have a "Claims" button then? I’m confused

Customer service had me try to create a MyPrime account. Kept getting an error indicating I was already registered. After sometime waiting, I'm connected to MyPrime tech support.  I apparently had a MyPrime account 10 years ago – before I had Medicare. First line tech support couldn't get me into MyPrime account, they created a problem ticket # and now I'm waiting some more. (Was on the phone well over an hour earlier)

This whole process has been confusing. I don’t understand the relationship between BlueAccess and MyPrime. Which one I should be using and when? Please help

UPDATE (morning of 1/4/2024)

1) The Walgreens claim showed up and is displayed in my BlueAccess account this morning (so, it normal takes 48 hours for a claim to appear?)

2) Someone in Customer Service is ill-informed and giving out bad information. Clearly, I DON'T have to login to MyPrime to see all my claims

3) Do I still need a MyPrime account? Do they handle mail order Rx's or anything else I care about? As someone with MyPrime support is trying to fix my account so I can access it
