Apologies for not mentioning that the sites were under controller management and not standalone.  Each site is being managed by a 5.13.22 linux controller in a Docker container (running on various platforms, not that it matters).  I didn't mention it initially as it was only the ER707 firmware that produced change, regardless, I have provided screen shots of my controller setups for the server and clients after getting the 'Cannot Recreate' note from the dev team.  Looking forward to hearing back.

I have tried the beta version 1.2.4, which lists as #2 bug fix a solution for an exception that occurs with policy routes and L2TP tunnels (which I have).  No difference, tunnels still do not come up on firmware later than 1.2.2.  I have provide access to the TPlink dev team to get in and have a look at the logs.  Will update as things progress.
