This document contains a detailed analysis of all the problems reported in the ProtoDUNE lessons learned document [DUNE-doc-8255]. For every issue observed in ProtoDUNE (and a few additional ones) more details are given, including the work that needs to be done to fully understand the root cause of each problem, the design changes that have already been done or have to be done, a timeline for the resolution of the issue, and a responsible person. This information should also be entered in an issue tracking system (sadly we do not have such a system available at Fermilab right now)
