I'm not seeing it either, after searching through the page source even. Availability of an RSS feed is the sole thing that determines whether I keep up with a comic or not. Kinda bummed that I'm dropping Fangs and Erma after just finding them because their publishing platform seems to be missing a basic feature.
edit: it does look like RSS is still mentioned as part of the service in the terms of service, though. Maybe it's still hiding somewhere? https://help.tapas.io/hc/en-us/articles/115005545248-Terms-of-Service
