There is a baseline problem underlying various issues experienced by users which is messages not being received yet no problem sending.
Some users experience issues in all profiles and some only experience issues with non-Admin profiles but all experience the baseline problem.
It seems like the baseline problem is very rare if we consider the number of posts in this thread and across the forum.
My post was to log another expression of this baseline problem not discuss a process to resolve. I have not wanted to execute a hack that might erase data without resolving the problem.
I have deleted a significant number of non-important conversations and archived others in case a database access problem might be a factor. No change.
Since my post in this thread my phone has completed an update to GOS, no change.
It cannot be ruled out that a cause could be the interaction between Messenger app and Google software components or GOS software security and privacy software or architecture.
One test could be to install an alternative SMS app and test its operation. Any suggestions for an alternative privacy protecting SMS app?
