Tech tip - problem with mobile testing tool

My game looked strange when I tested it on mobile phones run by 'appetize.io'.

There was a thick border around the boards of players. And the game seemed to hang when I pressed a button.

I thought maybe Chrome was adding an outline when an 'input' element got the focus. So I tried setting 'outline: 0'. This did not fix the problem.

However, when I tested my game on mobile phones at 'browserstack.com' then everything looked fine.

I realised that maybe there was a problem at 'appetize.io'.

However, 'browserstack.com' only gives you one free minute per device. Whereas 'appetize.io' gives you 30 free minutes a month. 'appetize.io' worked fine for tablets.

This was a few months ago. Now my game looks fine on mobiles run by 'appetize.io'.
