Can no longer add pages to existing PDFs offline?

Hi, folks. I've been using Acrobat Pro for years, and still have it installed on my Mac where I use it daily. However, I just tried to add a page to an existing PDF and even though I'm running Pro (though it calls itself only "Acrobat" unless I click on the title, whereupon it says, "Acrobat Pro"), the software forced me to upload my document to the cloud just to add a page. Previously, I'd been able to do this all offline, but the ability to add a page now seems to be online-only. Can someone verify this? I'm running 24.002.20759. It seems completely insane that they're removing offline functionality and making it cloud-only. I really hope that's not the case and instead I'm just doing something wrong....

Thanks!

Edit: To be clear, I can still add pages, but I must now upload the PDF, add the page online, save the PDF, then re-download it.
