New user trying to login for the first time.
Went thru the Strava auth flow and granted all requested privs. Returned to Flink to login, but any attempt to login or signup provides a very brief flash of my user page, then immediately dumps me back on the login page with an unhelpful “Sorry!” message and expired session (url=https://flink.run/login?notify=asphalt:user:session:expired). Have not yet created a Flink-specific login. Tried both Chrome and Opera on MacOS 10.14.6, athlete ID 722968.
Please advise how to continue.
