Unauthorizing: revoking @steemauto access from your account (leaving steemauto)
No,
you can set that to 80%
That is just an option to make sure your voting power will not get lower than that limitation.

Ok tell me this, why @steemitbaby my wife is following the trail of @dcooperation and she upvotes automatically with 100% when @dcooperation upvotes any post.

Why I can't set my account upvote with 100% as well ? I am authorized !

in the trail settings!

do you mean that I have to choose : FIXED VOTING WEIGHT ? I tried that and the VOTING WEIGHT (%): I put 100 , but my account is not upvoting anyway. TIME TO WAIT BEFORE VOTING (MINUTES) 0 . What wrong I am doing ?

Yes!
make sure you changed 'voting power limit' and that is not 100%! for example, change that to 80% then all will work well
goodluck

I still can't understand why it's impossible to make it 100% , I am a minnow and I want to profit the maximum from my upvote, 80% is not interesting for me, it's better to make manual upvotes from @clixmoney in this case.

steemauto is not designed to save upvotes and broadcast them when you had enough power!
power is different than upvote weigh, always you can find another service better than steemauto:)
I already explained and said how to configure your settings to vote exactly like @steemitbaby
