I unpinned my second very small store from my profile because it was shown as the first one in ´´my stores´´ profile, even though is not really significant. Is that going to affect anything? I noticed in the last few weeks that the views almost stopped and I am starting to think that the unpinning was the reason.
Personally I did not notice changes in my stores’ views or sales when I unpinned them, because I think customers rarely check the profile and even less the other stores. But maybe if you promote a lot your profile you have more visits, especially if it was showing first. You would need to know if you got more views on your other store instead.
