We are investigating an issue affecting calling functionality for some users. Some users may be unable to place calls to Donna, and Donna may also be unable to receive or place calls with those users.
As a workaround, we recommend enabling VoIP calling if possible. To do this, open the Donna mobile app and go to Settings > Preferences, then enable VoIP as your calling method. Calling Donna directly or retrying when Donna calls you may also work.
Our team is actively investigating the root cause and will provide another update as soon as more information is available. Feel free to reach out to support@askdonna.com if you have any questions.
