I am having an issue where sometimes I dont receive incoming texts. AT&T has said it could have to do with the Advanced Messaging setting and I saw you post here - https://textra.uservoice.com/knowledgebase/articles/894480-t-mobile-at-t-verizon-missing-messages-rcs.

The problem I am having is that I can go into the stock Messages app on my S9 and disable Advanced Messaging. However, as soon as I start using Textra again, the setting switches back to Enabled. It can only be disabled within the stock app and re-enables as soon as I make Textra my default. So I cannot use Textra because I will miss messages.

Is there a way to disable AT&T Advanced Messaging and still use Textra?
