It's often very slow at updating tracking information. The shipping company will show updates, but this app takes awhile before displaying that same info. Also, a recent update broke the times given. For example, the app said a delivery was made at 3pm when it was actually made at 8am. I can't find any settings to fix this and it's not covered in the help section. I also was unable to find a way to contact them. The new ads are also huge and annoying. Finally, I miss the old name Arrive.
