For over a week I had been frustrated with twitter on my Samsung Note 3 due to the lack of push notifications occurring. All the steps suggested by twitter support in the email below had already been tried by me several times. So if you get the message when trying to turn on push notifications “you cannot connect more than 25 devices to one account” by all means try the steps below. But if that doesn’t work, you will have to send an email to twitter support and wait about a week for it to be fixed.
