The irony is "twitter will provide updates when it's fixed" is about as vague as one can get. If the site is fixed who needs to be provided an update by that time? Until then access is restricted. lmao.
Maybe they are working on converting third party sign in's (google accounts) to match with replacement accounts? Currently there's no way to convert an established account created using other sites, without creating another account, & one can't transition an account over. Maybe they are addressing this issue?
API is development, could even be a third party update requirement.
