Litchi after changing mode from track mode

[hea-kun]

After using the track mode with Litchi on android, changing the mode to fpv without performing the tracking stop operation, the controller no longer accepts gimbal up / down operations. You can switch between horizontal and downward mapped to custom keys.
The aircraft is a mavic pro platinum.
Are you in this state?

It seems to happen on certain phones.
This failure occurs with xiaomi mi max2, but mi max3 works fine.
The version of Litchi is 4.17.0-g.
