Advanced Activity Feeds / Wall Plugin of socialapps.tech apparently doesn't have an option to unhide activitivies from certain user that previously marked hidden? I even tried on the demo site and result is the same.

Hi themrt,

Thanks for notifying us for this issue, checked it on the staging setup and yes, this issue is existing. We will fix this in the Advanced Activity Feeds / Wall Plugin and fix will be available in the next plugin upgrade. 

Please feel to write to us here: support@socialapps.tech in case of any issue or query. Our support team will be more than happy to help you out.
