Thanks for the tip! After installing Discourse app on iOS, I was unable to login. My forum account was setup to use TrainerRoad as login (I did not create a separate login). Anyone else with this problem?
Sure, but I did NOT create a new login for the forum. I chose the option of using TR Account, instead of creating a username/password for the forum.
If I attempt to login directly to forum with my TR username/password, it will not work (as expected). Therefore it appears my forum account is using singe sign-on (SSO), and that is not supported in Discourse app.
EDIT: on another thread someone mentioned forum authenticates to TR using oauth
Oh well, I’ll toss the Discourse app and go back to viewing on iPhone browser. The phone browser works well on this forum, so its not a big deal.
