For some reason electronics aren’t being sent where it’s needed.
Image shows an example of what I mean.
No traffic problems here that I know of.
You could click on that little arrow next to where it says 30 electronics. Then you can see all the buildings that require electronics. There are different colors. Not sure what they all mean, but if they are green than that means they need that resource and are connected to the road. I think yellow means the same, but the storage is full. And red means that it requires that resource, but the buldings are not connected. It might give you some insight into what’s happening.
Also, it could be a district problem.
Also also, maybe unrelated, maybe not, you need more workers.
Figured it out. I deleted all districts and it got fixed.
