Countless iOS apps experienced problems launching Wednesday evening, according to multiple reports on Twitter and crowdsourced user reports on Downdetector. The issues seem to have started around 6:30PM ET, and Spotify, TikTok, Pinterest, Tinder, and more were affected, according to Downdetector. I personally experienced problems with Spotify and GrubHub, but they are both working for me now, so it seems apps are starting to starting work as normal again.
