Clipper in Chrome is worked again at the moment In Safari still does not work. Re-installing, clearing caches and web data did not help.
Web Clipper does not show list of notebooks and tags. It does not work in Safari and Chrome. (Mac os Sierra, Clipper 6.9.2) I had a Basic account - it was worked, then I pay for Plus for one month and return in Account manager back to Basic (do not want automatic payment) and list disappeared.
