We are using CIVICRM 5.463.
We have Twilio SMS set up and it did work great for a period of time but now has stopped working for individual and group texts.
The send outbound SMS cron job is completing successfully.
When you send the message, CIVICRM displays the message that the text was sent successfully.
Yet no texts are being received by anyone. The process ceased to work about 2 weeks ago. No technology changes coincides with this timeframe.
Any ideas where I should look to figure out the issue?
