Thank you for reaching out to us on our Community page. We are very sorry that you were having problems uploading files to your library. This can occur for a few different reasons. If you are uploading a rather large file the process can go a little slower. Also, if you are having any connectivity issues this can cause the uploading of files to slow down. It could also be a browser, or plug-in issue, in which case you could try a different browser.
We did not receive any reports of site issues or slowness during the time of which you posted. Earlier in the day however, we were having some slowness in accounts if that is when you were trying to upload your files. You can always check our Status Page for real time updates of our site.
