Tested with:
- RFD4031 + TC21
- RFD4030 + TC21
- TC200J

After we use the locate functionality, the inventory stops automatically instead of only stopping when the reader is pressed for a second time.

Please check attached video (https://we.tl/t-R7E3A1FEX) in which we executed the following steps starting from minute 00:26 (before the video shows the configuration of the trigger mapping). 
00:27 enter Inventory screen to demonstrate that the Inventory is working properly (= that the Inventory reading stays active until the user pulls the trigger again to stop reading).
00:39 Enter Locate screen to locate an EPC. This works perfectly fine as well.
00:53 After coming back from Locating Screen to an Inventory Screen, I can only read bursts of EPCs and the reader automatically stopps reading after a couple of milliseconds instead of continuing to read until it's stopped by the user.


In our App, we experience the following behaviour:

1) We pull the trigger to start the Inventory

2) INVENTORY_STOP_EVENT is being sent by the Zebra API after a couple of milliseconds automatically

To start it again, we have to pull the trigger again but it automatically stops reading tags like described in 2) automatically.

Attached you can also find the trigger settings being used and the reader info.
