Duplicating Admin Activity Emails for all Sites in the Network about pmpro-network-subsite HOT 1 CLOSED

For now, we are recommending the following fix until the issue is resolved

Complete the following steps for each site in the network:

1. Temporarily deactivate the “Paid Memberships Pro – Multisite Membership Add On” Add On on each single subsite from the Plugins screen in the WordPress admin. This will allow you to edit Advanced Settings on the subsite.
2. Navigate to Memberships > Settings > Advanced Settings on each single subsite.
3. Change the setting for “Activity Email Frequency” to “Never”.
4. Save Settings.
5. Reactivate the “Paid Memberships Pro – Multisite Membership Add On” from the Plugins screen in the WordPress admin.
