Error: There was a problem releasing your SIM. Try again later

I am having a nightmare trying to unclaim my borons and release their sims so I can transfer them to a different account. I am now getting the error (in the web - console.particle.io) “Error: There was a problem releasing your SIM. Try again later.” when I try to release the sim.

If I try to deactivate the sim, I get “There was a problem acting on your SIM: server_error”

Any help?

The last couple of days the sim release queue has stacked up at the MVNO side - so we are seeing delayed activation/release times.
Please try it again.
