I have issue with souncdoud app. My phone is Huawei P9 (non lite) and often when I lock screen after few seconds music stops playing, app is killed. Firstly I wrote to huawei support but they are claiming that this is probably apps fault because I did all the things on phone like turning off power saving, exluded app from optimisation list and etc. And original Music app is never killed. So Huawei insisted that I should write to Soundcloud support. So maybe you heard that annoying problem and have a solution?
