It took a lot of time uploading a picture and some pictures isn't loading. It's very slow. Please fix that thank you!

I still prefer the older version bc no matter how large the amount of the MB, I can still upload it faster.

Because images were being saved locally to your device and not to your account which is the reason why it was faster. Hopefully in near future it may get faster depending on your connection.

iPhone 5, iOS 10.2. Thank you! I really love this app! 

This mostly depends on the image you are trying to upload. Luckily I have added an MB limit to try and prevent large images from being uploaded for longer loading times.

I personally have not come across any slowness. Could you let me know your device and iOS to possibly try and help solve this?
