We have an issue where people can no longer proceed through the oAuth code grant login process on any Android device. It has actually been an issue for some weeks and we are pretty sure it is no happening because of anything we changed.
It seems we are getting stuck at the Login Transfer page that is shown in the browser after Fitbit credentials are entered. This is our URL
https://www.fitbit.com/login/transferpage?disableThirdPartyLogin=true&redirect=%2Foauth2%2Fauthorize%3Fclient_id%3D22CRQL%26redirect_uri%3Dileadit%253A%252F%252Fileadit.app%252Fauth%252Ffitbit%26response_type%3Dcode%26scope%3Dactivity%2Bheartrate%2Blocation%2Bnutrition%2Bprofile%2Bsettings%2Bsleep%2Bsocial%2Bweight%26state
We end up here in the phones browser https://www.fitbit.com/login/transferpage but never get back to our app. It was previously working, so we are at a bit of a loss.
I have posted the authorise URL into postman and we recieve a HTTP 200 as expected.
Where should I be looking?
Thanks.

Issue turned out to be at our end and was related to Activity/Intent Filter changes related to Android 12 support.

Hi @MrLane
I tested the URL in my web browser (Chrome on Mac) and it works. Are you having this problem with all new authorizations or just a few? Do you have an approximate timeframe when the problem started happening? Also, would you please provide me with your authorization URL? You can send it to me via a private message, if you prefer. I'll asked someone on my team to test it with their Android device.
Best,

One more question. Can you confirm the steps the user is following when the hang occurs. For example
- The user clicks on the authorization URL in the mobile application
- The user is asked to log in
- Once the user logs in, they are redirected to the consent page but the redirection hangs before the page is loaded.

Hi, I am still getting some feedback from others in the team, we are all working remote at the moment. We cannot pinpoint an exact date when this started as yet, I am waiting for a response from those who originally reported the issue. Loosely, I would say this was an issue only this year. We don't know how widespread this is as we don't have a large enough userbase currently, but I am asking a few people to test.
In terms of the steps, yes the user clicks on the authorisation link in our app, the browser opens and navigates to https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=22CRQL&redirect_uri=ileadit://i...
In my own testing, if the users browser isn't already logged into fitbit.com they will be asked to log in and with a successful login they will be asked to select permissions for the data fields. Clicking Allow does not work, nothing happens.
If the user is already logged into fitbit.com they end up at the transfer page, which then hangs. I am surprisingly getting an indication (in several browsers) that the site doesn't have a certificate...which is very strange.
When I open the link in InPrivate mode, I can progress to the login page and then the permissions page, but then hang on the transfer page, as in the case of the user not having been previously logged in.

I'm ignorant about certificates, but the mention of same reminded me of this.
