I haven’t had it pop up for since the first months buddy system rolled out. Sure I don’t live in a city but there are a fair amount of pokestops around where I live. I could be wrong and it’s working fine but I’m curious if this is effecting anyone else.
My understanding is that it only works for stops never spun before.
Last I heard, the feature was also broken and each buddy Mon would find a unique location once on the day it hit ultra buddies…and then never again. No clue if it’s been patched since then, but seeing how infrequently it pops up, my guess is it hasn’t been.
