Instagram videos just say sending when uploading on LTE?

I have an iphone 5 4G
LTE and my instagram always used to upload videos with any range of time in seconds. Now all it says is " preparing" or " sending" and it never ends up uploading. It now uploads only on Wi-Fi where it used to upload anywhere from 4G to LTE. Is this a bug? Because problems with my instagram started happening after the flats few updates

  • Why does my iPhone not say 4G or LTE anymore? I had a huge phone bill so my parents turned off the data for my phone and now where it used to say 4G or LTE it is blank? Also I can't turn on iMessage unless I'm on Wi-Fi?
  • Why does my iPhone 5 say LTE instead of 4g? I bought an iPhone 5 and it's connected to T-Mobile. At first it had of course the bars and it said T-Mobile 4g. Now it still has the bars and says T-Mobile but instead of 4g it says LTE on the top left corner. Why is that?
  • Uploading videos to Facebook from iPhone 5? Hi I've just got an iPhone 5 for Christmas and I can't upload my Christmas videos to Facebook I've got the app but the videos won't upload they haven't got a tick next to them to let me upload them Does anyone have any ideas? My iPhone 3 in the past would let me do it
  • My photos are not sending in group messages, but are sending in individual messages? I'm with Straight Talk Wireless. At first my pictures were sending in the group message but now they are not. I don't know what's wrong, all my settings are what they are suppose to be, and I'm currently on an iPhone 5s IOS 8.4.
