This is a debate within the anarchist community for several reasons. First of if we were in a pre-revolutionary era and a lot of people were already active in some sort of non-hierarchical groups and about to take over society, yes at that point voting would be damaging to the cause. Currently we are not at this point.
Also many anarchists consider direct democracy as way going forward towards autonomous local organisation. Rojava would be a recent example of this case.
Personally, I think it is meaningful to vote. The important thing is not rely on it. One can easily vote and do community-organising as well. I agree that voting does not challenge any of the hierarchical structures that are in place. Not voting, doesn't neither. At least at this point in time.
