I have not had a daily Summary since July 12, 2018. I posted this as a question on the regular forum and did get an email from another community member with the same issue.
In attempts to resolve this I have gone into my preference settings several times and updated the settings. This has not restarted the daily summary.
When I set the preference for All Activity I do start getting emails. However this tends to overwhelm the inbox. So I would prefer a daily summary.
Once this is working if you wanted to add a setting for 2 daily summaries ( AM and PM ) that would be great.
