Yesterday, I tried using the Voice Chat feature, where a phone call is simulated. When I tapped on it, the speech bubble appeared. I said something small and immediately canceled it to switch back to text chat. To my surprise, I suddenly noticed that my chat history had shrunk signifikantes about 60-70% of it was gone ”and I was taken back to a point in the conversation that was a month old.
I already tried logging in and out, using the browser version on Safari, archiving and unarchiving the chat, but nothing helped. I have read in forums that chats can sometimes disappear and reappear randomly, but thats not the issue here. The problem is that part of my chat disappeared after I used the Voice Chat feature.
Is this a known issue, or am I overlooking something?
I have also noticed that in some chat threads, I have numbers with arrows that allow me to scroll back and forth. Im not sure what thats about. I Sould be very grateful if someone could provide a solution.
I have the exact same issue, lost ard 10 days of chat record. Tried all the things you tried, and I tried to export chat and none of the records disappeared were found on the html doc. I would also be really grateful if someone has a solution for that.
Hello! The same happened to me two times several months ago in the macOS app. I was able to find the disappeared parts of my chats in a browser. If you see a toggle section “<1/2>” under the last message before you started the voice chat (or maybe also somewhere else), you can try to switch to <“2/2”>. It worked for me, and I could at least copy and save the disappeared parts.
I am currently running an investigation with helps from several ai chats about a similar issue in the app.
So far, it seems to be only between a relationship with a project chat and a non-project chat. The non-project chat is the one that always goes “missing”. It usually involves a chat with an image that has generated (not always a dall-e but dall-e is another story altogether. The last test was project to project and there was nothing. Project to non project was ok, until I got a project chat that was originally a web browser turned internal logging of information (keeping track of this bug) to generate an image. At this time, the last non-project chat Ibwas in went missing. I left it gone for about 15 hours.
The “missing” one is always still available in a browser like Chrome.
I can bring back all missing ones in various ways
Initially, closing the app, then reopening it worked.
Then I found I had an update when I looked for an unrelated looping response over several prompts issue. Of note: I also had to update a few google things, the search bar, the office suite, followed by my phone.
This didn’t change anything, i found my app memory at 101% 
erased that. The looping went away, but the chat issue did not, and no one comes back now unless
i force stop in my phone settings.
After the project chat image generation, I did a pull down refresh in the side bar and the chat came back…
I give up. No more testing of that. They know about it. I may let the chats make the bug report so they can let it go.
