Re: Zoom issues with latest update
Just to follow up.
Support responded saying that during an update or new install the app runs a performance check and if areas of devices resources are deemed inadequate then certain features can be disabled.
It seems that my tablet's graphics are not up to scratch, probably due to the larger screen, so the zoom function has been disabled.
The only fix they suggest is using a more powerful tablet or a smaller device such as a phone.
I'll just find a different game to play on my tablet.
