Hey @dcki ,
Thanks for your patience! I can’t see anything blindingly obvious but what I have done is purged the CDN cache for your site, just in case there’s anything awry there.
As for how our RBAC cookies work, I can’t add any more to what @jonsully has already contributed in this thread but what I suspect is that your cookie is lapsing after 1 hour, as per design (but also, recognisably, perhaps undesirably).
