Yes, the Samsung approach to delivery reports is to send a notification, as opposed to a simple [emoji736] or "Delivered," as the Google app used to do.
Has anyone gotten this to work using Google Messages? S21 Ultra UL on Verizon. Not using RCS. Stock app and Textra delivery reports work fine. Have cleared cache, data, uninstalled, reinstalled, cleared network settings...any thoughts?
I wasn't having any problems with any devices until now with the S20, which itself had been working fine. I'm currently trying phone MAC instead of randomized. Seems better so far, and the speed has increased.
