Now when I start my workout (activate apple’s workout app) then start my Cero app, like I always did, the Apple workout app overrides the Cero app and Cero stops counting down (happens after the watch goes into sleep mode). The only way I can get it to work is to restart everything, turn off the watch, then turn it back on. Before the last update this was a 5 star app for sure!",
