Hi, it looks like there may be a bug in the way the indexer/message optimizer works. I bought a new phone and installed textra on it. I opened textra and it indexed existing messages, and received a message as well. Then I did a restore of all my previous sms messages from my old phone. Textra pulled in all the messages I had sent to my friends, but does not display any of their responses. All of my conversations look like one-way conversations where I sent them messages but never got responses. The default messaging app does show all of my friends' responses, so I know they were imported successfully.
