Never Combines files the first time. Maybe the 10th or after 100 tries adobe will combine the files suddenly like there was never a problem. It's the only reason I pay the premium, and it works only when it feels like it. It's just two pages. It won't combine them until it wants to, if ever. My least favorite part of doing paperwork is praying adobe will do it's job today, the only job I pay it 10 bucks a month to attempt. 🙏
