I've preached twice at my church. Both times, I have received lots of positive comments from people, both in person and by text, thanking me for what I said and encouraging me.
I also lead a setup team at church, working for an average of between 1 and 2 hours each Sunday. I hardly ever get encouragement for this work.
This is not me complaining about not being encouraged in setup stuff - I do it because it needs doing, I enjoy it and I'm good at it. But I am aware that the work that the setup leaders and setup teams do at my church is very overlooked compared to the 'up-front' stuff like preaching or leading worship. I think it's a shame that people put so much emphasis on something like preaching compared to something like setup, as if preaching was more important or more difficult than setup.
