So recently I've switched from a xiaomi to a Huawei P9 and so far I'm regretting it. Notifications from my apps are delayed until opened but the worst part is that every time I push the clear recent apps button the cm security applock I've installed stops working, and I've tried everything from switching on usage access, ignoring optimization,and drawing over other apps but nothing works. Please someone help me before I'm tempted to go make a refund.
