I would need to know more about the particulars of your situation to provide better advice. However, some thoughts: 1. Knowing the tech would definitely help. However, learning complex tech is not easy and takes significant amount of time. For some, it may not even be possible. 2. Is there a senior dev in the team with whom you can share project ownership? A person you can bounce ideas from? 3. Understand what your job really is. What are you there to manage? The timeline? What work gets prioritized? How work gets communicated to stakeholders? In many cases these do not require tech expertise since the time estimates, complexity, etc can be provided by a tech lead and you can work on negotiating those with stakeholders and deciding what is in and out of scope based on said estimates. However, it requires you to have a lead that you can trust.
