Adobe CC Teams Acrobat DC Pro Sign

When we tried to use Sign for a a report with a 140 pages we found the limits are a platry 100 pages, 10 MB's, and 150 transactions per annum. These are impractically low for any small business so I will be making a compaint. We hold 5 licences in CC Teams and need a minium of 200 pages and 20MB's for a large proportion of our repoarts. The only option for sufficient pages and files size is Business which is a 100% jump in cost. We are keen to use Sign for our documents however Adobes restrictive policy must limit taekup by small businesses. We well defer using Sign altogether until lmits are more reasonable.
