Have the possibility to change the verbiage in the mobile interface.

Example, when an invoice is approved but the limit was not sufficient to move it through, the second approver receives this notice
"Please approve as verified by XXX"

It should read
"Reviewed and approved by XXX"

Also, they see "Assigned to you by four eyes principle policy" Four eyes principle is mainly a finance term. Other approvers won't necessarily know what it is.
Should be replaced by "Approval required as per corporate approval matrix"
