I’m trying to login to the IDE via my Samsung account this morning and getting:
## Error Message 
Sorry, the resource you want to access is forbidden, so this request has been refused.
If you have any questions, please contact the administrator.
Try an incognito window.
If still doesn’t work, it could be temporary.
And be sure you are starting at https://account.SmartThings.com - not any other URL!
man it’s just one thing after another.
I haven’t researched, but I would hope that it is impossible for a website to determine if the browser is in private or incognito mode.
Logins to most websites (including Samsung Login) may require storing a session cookie, but incognito mode does not prevent this. It just destroys the cookie upon exit.
