Looks like Twitter decided to not play nice once again, to developer Joaquim Verges and his baby, Falcon Pro. This happened a few months ago when Falcon Pro hit the 100K tokens, and was unable to have new users join the Falcon fun. Since then, Verges has been working hard to workaround that dumb guideline, but that work has come to an end, and he had to lift his app off the Play Store.
If any of you out there are on version 2.0.3, and cannot sign in, Verges has provided us with an apk of 2.0.2 that you can grab and use. Hopefully you had a token before this new 100k mark was reached, or you will still not be able to login. So hit the link below to grab the apk of 2.0.2. Let us know if it is working for you.
