I had a call while taking the challenge in Sololearn mobile app. I was not able to go back. So I attended the call and get back to the challenge after three minutes.
The test was automatically completed and the result was zero. I wish the test need to be paused while receiving the call.
I have a solution.
Just turn of internet connection and answer the present question.
U can call without any problem.
After call ends, connect to internet again and click on try again button.
No worries. 😄😄✌✌✌
