Hi, Sergiy:<br /><br /><br />Please&nbsp;find attached your edited document, which I carefully reviewed. I hope that you find the suggestions helpful. If you have any questions, please send a message to me via Editor World.<br /><br />This was a very interesting, comprehensive and informative study. I had no idea that app testing was so complicated. You did a great&nbsp;job!. I simply fussed and finessed. If you have any concerns or questions,&nbsp;please let me know.<br /><br />Best wishes - George (TypeRighter)<br />I am usually available for editing between 6:00 am and 10:30 pm (EST).
