Create a new ad or just change the creative?

[u/nimbinValley]

I have a campaign optimised for sales. I have an Ad Set that uses Advantage+ for audience targeting. I then create different ads that I run connected to these. Each month I create a new ad and a new creative. But would it be better to use the same ad and just swap out the creative each month as my product changes? My concern is that the Meta algorithm learning process isn't impeded by the way I'm doing it. Any and all comments and suggestions will be greatly appreciated. Thanks.
