Trying to diagnose AMG lab commander timer problem

I recently acquired a AMG lab commander timer OLED version but noticed the Practicore Android app will not pull the time correctly(pull time will only get the first shot time and quite a few 0s after the first) from the timer. The BLE connection is established(I can start the timer remotely from the Practicore Android app). I am trying to diagnose this problem so I am wondering if anybody else have the similar problem?

I haven’t got a response from AMG lab so was hoping to get some luck here. I understand it is probably the timer’s problem.

Edit: I got an email from AMG lab, will update if possbile.

Edit2: Alex called me and helped me clear the memory of the timer and it’s now working perfectly. Great customer support!
