My iPhone FiverglassRV app stopped working. I typically use it on my phone to look at new posts and it stopped displaying content yesterday. I tried logging back in and it wouldn't accept my login. I verified my user/password using the website to logoff/logon and it still works fine there. I deleted and reinstalled the app on my phone and after opening the app it presented an error that there was a problem contacting fiberglassRV and to contact forum admin. I tried going through authentication again via the app and get "Log in failed. The operation couldn't be completed. (Forum SSO error 2)". It offers me to do a password reset but my password is fine on the website.
I use the mobile version to read posts and the android app to post when I want to put up pictures. Every once in a while one will get uppity. I've found clearing my data, that is, cookies, cache, etc. solves the problems.
