So we moved our organization from DocuSign to Acrobat Sign via Acrobat Pro subscription. Our users start encountering a 100 page limitation. Support says you need an enterprise plan to move up to 500 pages. Looked at the enterprise plan, for some reason it has a 150 transaction limit, but the cheaper option is unlimited? Who is making these decisions? So you have to pay more to get less? This is an incredibly strange decision. Imagine if Microsoft told its customers they could only send 150 emails on 365 unless they move to a cheaper plan.
