I want the user to select an account with the account picker via newChooseAccountIntent(). When setting the allowableAccountTypes with arrayOf("com.google") only accounts with a google email address are shown. But whenever I enter something else to filter for a specific provider (like yahoo or gmx) no matter what or how I enter it (like yahoo.com, com.yahoo, yahoo etc.) there are no accounts shown. But when passing null all accounts including those with a yahoo or gmx address are definitely listed.
A similar question was asked in this post 7 years ago but all provided answers didn't solve my problem. Pick an email using AccountPicker.newChooseAccountIntent
