Users are having issues attaching documents to compact activities that are larger than 1MB in size. After clicking the Upload button, the progress graphic just keeps turning and the file is never uploaded.
Here is Appriss' description of the problem:
The development team found a bug that is causing file attachments >1MB to fail in uploading and they are working on finding a fix for it.
