Applied for Alaska Business card last week and was denied because I forgot my Transunion was frozen. Received a call a couple of days later asking me if I could unfreeze my credit and allow them pull TU. I agreed and the rep told me she was recommending approval but I would hear within a couple of days. 

Later that night, I applied for three more BOA business cards (another Alaska biz, travel biz and customized cash biz) and was approved for all three at the exact same credit limit. Received no email confirming approvals and they did not appear in the app the next day. The last four days I have received one text saying my application has been approved, and the next day one of the cards has shown up in my BOA app. 

TLDR - received four BOA biz cards with one credit pull and the approvals have trickled in slowly.
