So i was checking out the add a domain section of the settings section and I typed in a domain and clicked the setup button, then deleted it afterwards and whenever i try and preview the app now it tries to direct me to the domain name i deleted and i cant preview the app.
DNS settings take a few hours to update. From what i remember, the worst case scenario is actually 1-2 days.
Its very frustrating to have to wait but sadly you might have to take a break. (Or work on something you don’t need to preview very often)
If the problem persists you can contact bubble support.
