We have been working for more than 2 years, not without problems and nuances that occur in the work of everyone, because we live and work in a volatile structure, when like dominoes can collapse everything.
BUT there is NOT ONE BUT.
Very positive manager, high quality Support, global enough and almost always fast solution of problems and nuances.
On the functionality and settings I think that almost everything is enough, you can clearly throw all the parameters and see what chain works, what result is obtained, you can figure out what goes, what does not go, on what geo and a lot more.
It is very cool that you can describe all the questions and problems and get quality feedback on each item with a breakdown of why and wherefore.
