Unstable App on iPhone 6

This app has always been far inferior to the UPS mobile app. Recently it added the ability to not load completely 50% of the time I try to use it. When it works the most I can do is see an estimated arrival date and where my packages are sitting for days while the transfer to the USPS for final delivery. Their smartpost service should be names slowpoke service.
