Device “old C” “exist” as a device ID in config of devices A and B. When you delete device “old C” on device A, (after restart) there is a handshake between A and B, in which info about all devices sharing folders (which A share with B) with B is also sent. In this info there is “old C”, because it is still in B’s config. If you have set B as introducer on A, “old C” will be added in device list of A without asking. So to solve this you have to:
- Unset introducer in all devices in device lists on all devices, delete old devices on all devices and set introducer in all devices in device lists on all devices.
- Stop all devices, delete old devices on all devices one by one, start all devices.
First approach is clearly more expensive, so I wrote steps to approach 2.
I agree. I have 6 devices on 2 locations and it is quite challenge to get online all at once so I could use approach 2. So I’m also missing such button or mechanism to deal with this situation. Maybe there is some trick that I haven’t figured out yet, @calmh?
