It works fine for me on Tapatalk.
I for one will miss it (probably).
This new thing had better be good!
I've had another message board I use frequently go through a similar migration and end the need for Tapatalk (not sure if it was the same underlying tech platform). It does take a little bit of time to get used to it, but you do get used to it. It basically looks/works the same on a mobile device as on a computer and you access via your browser vs Tapatalk.
