Same problem but I went into my existing templates and edited one over
and over to list yesterday. I understand some cannot access their
existing templates, so this may not help everyone.
I haven't reads the other replies and this may or may not help. I
haven't been able to save templates for a few days. I've gone round and
round with eBay. BUT. When I noticed sellers were having trouble
accessing their templates, I went to check mine...
