Prior authorization

I have gotten prescribed Zepbound by my provider, however the insurance is requiring a prior authorization. Insurance has stated they need additional information such as clinical notes and a questionnaire filled out. The provider took too long and the PA was placed on hold. I had tried reaching out to let my provider know, but the call goes to a call center and it takes about a week if I do get a reply to hear back from the nurse. I'm wanting to see a new doctor and request the same medication and have them place the prior authorization. I have the appointment Monday, however my current doctor just submitted additional information for my prior authorization on Friday. Is it going to cause issues if I have a second doctor prescribe the same medication as well as submit a second prior authorization? This new doctor is much more responsive to patients in a timely manner. Also with this new doctor, multiple of my family members see him and have prescribed Zepbound with a very quick prior authorization process.
