I was publishing some funny article titles in development and wanted to share them with my partner. Naturally, I set up a ngrok link for easy sharing. I texted him the link a few times and even though my provider, t-mobile, said it sent, he never received them! He was getting all my other messages/links/etc but not the ngrok links. I've tried one other verizon user who also didn't receive my link.

Is this just a weird coincidence or does verizon block ngrok? Not seeing anything on a quick search. Note: not having an issue w/ any other mobile service providers!
