As announced last month, today marks the beginning of callback URL whitelisting enforcement. Apps using Sign in with Twitter who have not whitelisted their URLs will experience disruption. To whitelist your URLs, follow the guidance in our May forum post.https://twittercommunity.com/t/action-required-sign-in-with-twitter-users-must-whitelist-callback-urls/105342 …
Thank you for information.
I added #AndStatus callback URI to the application's settings at https://apps.twitter.com site and was able to access Twitter via AndStatus again.
