Clone channel has incorrect signature and does not sync files/pics
I created a second hub (at a different TLD for the same SLD), and I created new channels by direct cloning from existing channels of the same SLD, but different hub-TLD (not by JSON import). The new channel's posts are not received by existing and synced contacts. From the old channel, the new channel's posts is displayed with red exclamation mark ("signature incorrect") - and vice versa.
Although I used the content importer addon, the new channel does not have the files and pics of the old channel. Uploading those or new pictures creates second folders that are named "(1)" on the old channel. Effectively, the new channel on the new hub is not useable, and I am afraid that deleting them and re-installing the hub will not solve the problem (I would not know that to do differently, and even then, the channel might be considered as "forged" with the correct signature).
