hi I have been using iPhones since the 3G and have always migrated all my data from previous iPhones. For many years that meant that I could go back to any text/sms conversations I had dating back to 2008 within the messages app. When opening a conversation that has correspondence in it going back a couple of years, it will only let me go back 1-2 years before it will bounce back to the newest one when I'm scrolling through my old messages. This basiclLy means I can't access those messages anymore and they are lost. I can still search for old messages but not manually go back. Any ideas?
