How to Redirect user to their subdomain dashboard, when signin at the main website

hello members,

I have recently installed a fresh and new version of wordpress multisite. I try using the Login Redirect plugin for the following situation:
"I want to redirect a user to his/her blog dashboard after signing in at the main mother site. The current situation is that the user has to see a warning message saying ---You attempted to access the "The Website" dashboard, but you do not currently have privileges on this site. If you believe you should be able to access the "WebTopik Sites" dashboard, please contact your network administrator--- I was wondering if the Login Redirect plugin can solve this problem?......

I have seen so many instructions here in the community, but some instructions applied to older version..and I can't seem to get it to work....Can anyone please help or point me to the right posts...i would really appreciate it....Thank you in advance
