I have been trying to login to iNaturalist all afternoon on Google Chrome iOS and Safari iOS. Picture 1- Safari, Picture 2 - Google Chrome
Browser, if a website issue (Firefox, Chrome, etc) : Google Chrome iOS and Safari iOS.
Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):
Step 1: Enter iNaturalist website address.
Step 2: Load page.
Step 3: Click login with Facebook then error message appears.
I have used this to login to iNaturalist.ca since making the account. No changes to my Facebook account have been made.
