"Anyone else getting about 90% pokeballs from PokeStops? (level 27)"

#PokemonGO: I used to get a good mix of potions and pokeballs, but for the last week or so I have been getting about 90% pokeballs, some revives, some berries, and very few potions (sometimes I will hit 10+ stops and not get a single potion). I'm level 27. Anyone else have this issue? via /r/TheSilphRoad http://ift.tt/2bctsAP
