Unlock Request and One Coastline Issue

I regularly drive between Kaohsiung and Taitung. (Once every week)
Obviously, there are a lot of area still need to edit and I tried my best to do so when I have time.

Tonight, I was going to edit road around Taitung Train Station and there is level 4 locked road and I am only level 2.

The main object is this junction which is quiet complex and in my memory I did quick fix 20 months ago.

I want to edit this junction with proper interchange and as well as some slow lane and fast lane separation to implement correct turn restriction on 馬亨亨 and 興安路.

Second,
This camera is removed by local government about two years ago but since it is level 4 locked.
I can’t remove it either.

Majority of Coastline from eastern Taiwan is wrong and I repeatedly saw user report that road in the water but there is nothing we can do.
I have seen map editor Twinwood tried a so call band aid fix that I also googled with same solution that does not fix the issue.

I just want to know if there are any other way to tackle this coastline issue or we really just have to wait that someday Waze developer will fix it.
