This forum not being tapatalk native
For me it's the opposite
I find that if there's a web option and an app option the app or 'mobile version' can be limited. Obviously that makes some sense with the mobile version
I remember back when the internet was on a standard phone line, and when it started to be available on handheld computers and mobile phones.
There was a big need for limiting the traffic, but it still took a week to load a page.
With 3G & wifi as long as you get a decent connection then mobiles are majorly powerful devices in comparison to the past, if your phone contact has limits then an app may possibly restrict the traffic for you.
Personally I prefer forums using the web - either the apps such as tapatalk may not support all the features of the forum software, and to frustrate my old man personality apps make the web look and function differently.
