I finished gathering some data in the field two weeks ago and then tried to send it to the server when I got back to the office. I tapped the send button and nothing happened. I thought maybe it was an internet connection issue, so I took it home to my my known working internet and still nothing happened. This is an older ipad running classic because the new version is not supported on it. Iw was working fine a few weeks ago. Any thoughts on what is wrong? Same thing is happening with my older model Samsung. Have you stopped supporting older devices running survey classic?
