My company uses an ap where I text code to a phone number and get a link. I click on the link and fill out a form and hit submit. It goes to our backend system and completes the request and sends me back a link. I never get the second link. I have check:
1. The number is not blocked
2. It does not matter where I am geographically, but I am on the East Coast
3. It has never worked beyond what I described but it does work find for my colleagues
4. I do not have Google Message Preview turned on
What else can I check. I have an Android 23 with Verizon Service
