Hi guys client that has one project with us created a second project on the dashboard but there is not sub selected there. She has 2 subs paid so not sure what to do here. I can provide stripe link to the advanced 499.00 sub existing if needed not sure if I should post the link here. I am not sure what would happen if I try to change this in the dashboard to advanced (will client be charged for third sub). Field for acitivty code is empty (actually some object showing there)
