No idea if this is Graphene-related at all, but I couldn't find anything online so might as well ask here: I use Google Messages, with sandboxed GMS but without a Google account, on Graphene (stable) for Pixel 8 Pro. I have noticed lately (since approx October 2025) that texts that I send to myself no longer appeared in my messages list (I often text myself things as reminders). After some searching, I found the thread of texts to/from myself in the "Spam & Blocked" list.
Strangely, the thread is not marked as spam or blocked. Other text threads that I've actually blocked do show up in that list, and they have a banner saying they're blocked and offering an "Unblock" button. Likewise, actual spam messages display a banner saying they're spam (or "looks like spam"). My text thread with myself has none of that.
In fact, the only way I can get my thread back in the apps main messages list is to block myself (being careful not to report myself as spam), and then tap the "Unblock" button. It's like, the thread has gotten sorted into the Blocked list accidentally, so I need to put it there properly before I can remove it properly.
When I do this, the thread will appear in my normal message list for a day or so, but eventually will disappear back to the Spam & Blocked list. Has anyone encountered this or know of a more permanent solution?
