I have another app, an organization's application that maintains a list of people and their contact information. so this app is specific to the organization. inside the app I can select a number of people to send a group text to which then opens the messaging app where I can type in the message and hit send. this worked in the standard Google messages app, but when I use Textra it displays a list of phone numbers all separated by semi-colons and only the first number on the list receives the group text. my suspicion is that the app developer only tested with messages and that messages is more forgiving of a delimiter than Textra. my suspicion is that Textra wants commas instead of semi-colons. there is no easy way to edit it. I wonder if Textra might be updated in this regard to have parity with messages.
