Firstly, I think you might be able to update to system version 7.2. Try this first to see if it fixes things.
Otherwise for problem 1 & 3 I suggest you contact support directly.
Problem 2 is an accuracy…
7.1系统
Problem 2 is an accuracy issue that is the topic of many discussions on this forum.
Best of luck.
非常感谢您的建议，但我所在的区域还未收到instinct7.2系统的推送，只能再等等了。
再次感谢您
