Terrible user experience for first time users - rejected when tried to re-sign for 2nd party

just tried to sign a pdf both for myself and a witness

first time I had system email witness I had previously signed my portions however when witness tried to sign the form forced witness to overright my signed text fields otherwise form would not finish ... needless I retried that process yet when witness received same pdf a second time for resigning it errored out saying already signed

needles to say your pdf signing processing is very buggy ...  I double dog dare your support crew to recreate above and see this bug in action

in the end I stopped using adobe to sign the pdf and signed manually ... so sad for adobe users
