Not your fault (and not really ours…). We had to eliminate “tokenized URL logins” and replace with SmartThings IDE login as a stopgap until V6 (ActionTiles) … coming … soon(?).
See: SmartTiles v5.8: Deployed to Blue & Green Editions. Release notes, etc. (follow this Topic for updates...) for lots more details and various workaround recommendations in the meantime.
Sorry
