Still no data for June and I can't find a way to report this error to them.
Why couldn't they just keep May figures until June data is available is beyond me.
The whole Steam survey is so FUBAR I've wondered for few years now why on earth they still keep it then.
Either give us real, comprehensive data from all active Steam users every month, or nothing at all. Don't include those who didn't use Steam for a month, don't use old data gathered who-knows-when etc. Reset the statistics to 0 every month.
