InfoPath form won't open in browser

This is very strange because it was working fine yesterday. I made some changes to my InfoPath 2013 form today, published it, and now users are getting an error - "This form cannot be opened in a Web browser. To open this form, use Microsoft InfoPath"

I've tried republishing a few times, deleted the form web part and added it back on a couple times, all the settings in the O365 admin center are correct, site collection features are correct. The only reason I can think of that it worked yesterday and not today is that I'm working on my home computer today, would that make a difference? Has anyone ever seen this?
