Hi Franklin - how big of a date range are you selecting? We see a lot of trips in your account so if you're selecting too wide of a date range, you'll have these kinds of issues. It's better to do it in smaller chunks. Tech Support recommends a month at a time.
If you're still having issues even after trying that, please let us know!
Hi Franklin. I had one of our developers who helped build Web Dashboard look into this for you and he thinks that it might have to do with your internet connection speed or your browser. What Internet browser are you using? And what's your internet connection speed?
