My company uses Adobe Acrobat, and we have around 5 users on personal accounts and 2 on personal Creative Cloud Pro accounts (using our company email). We recently got an email asking us to switch over to the Teams plan. I have noticed they are trying to charge us over 2x the price of what we are paying now for the Teams plan.
I was wondering if we actually need to / are breaking any Terms of use by continuing to use personal accounts for business.
