Imessage issues
I have an imessage thread on my iphone 11 that has suddenly had texts from the past disappear. Everything we’ve texted eachother from like 2 days ago and beyond has vanished and as i send new texts the ones that havent vanished are slowly disappearing. Im really sad ): i really love this text thread and i like to back and read them and i cant now. I have my settings to keep messages forever, they dont expire. I also have over 20Gb storage available on my phone so im just really confused about whats happening. I turned iMessage on and off, i updated my software. Its not deleting any other threads, just this one imessage thread. Im just not sure what to do anymore ): thanks for any help
iPhone 11, iOS 14
