I recorded a WMA audio file to attach to a feature in Collector. When I browse to a folder to select the attachment, the WMA file is not visible in the folder. I'm able to attach the file through the Editor in the ArcGIS Online web map. Is it possible to attach audio files to features using Collector on Windows 10?
I'm using Collector version 10.4.0.0 on Windows 10 version 1511, and document and video attachments are working.
