I have the same problem on Huawei phone, so it is not a problem for Xiaomi only. Each time my child has low battery (under 15%), she is able to switch to ultra save mode and after going back to normal mode KSK does not work, it has to be manually activated - which is againts its assumptions. Of course she intentionally lead to low battery and in ultra save mode she can use whatever she wants. The programme, in its current shape, is pontless. Hope you will find a solution, since it is a well rated paid for application! Localisation may also be easily switched off. It shouldn’t be so. Has anything new appeared since the last posts? Thanks.
