As of July 4th 2023, Old TweetDeck has been unplugged, Preview is the way and will require a Verification. Meaning Better TweetDeck is obsolete and will not work anymore.
Thank you to everyone who used it, contributed to it, and supported the project over the years, whether it was by reporting bugs, suggesting features, or donating to the project. It truly has been a wild 9 years and I'm glad I could help so many people with my "little" project. I wish it didn't end so suddenly but it is what it is.
So long and thanks for all the fish!
