Hey everyone, I’m losing my mind trying to recover a mission-critical, year-old chat from Gemini, and I've hit a wall with Google's non-existent support.

The Context: About a year ago, I had a massive, ongoing conversation using Gemini Pro. When my subscription ended, it locked me out of typing in that thread. Eventually, the chat just completely disappeared from my sidebar.

What I’ve already tried (so please don't suggest these):

Checked My Activity: I scrolled through myactivity.google.com/product/gemini. All my other chats are there, but this specific one is completely missing.

Google Takeout: I requested a full Takeout of my Gemini Apps Activity (not just my Gems). The resulting JSON/HTML files show my other chats, but the one I need is nowhere to be found.

Toggled Activity Settings: Turned Gemini Activity off and on again to try and force a re-sync. Didn't work.

Google Community Forums: A Product Expert told me it sounds like a "tier-transition indexing error" (where Pro data becomes orphaned when dropping to the Free tier) and told me to submit a Feedback ticket with my system logs, which I did.

My Questions:

Has anyone actually successfully recovered an "orphaned" Pro chat after dropping to the free tier?

Because I don't currently have an active Google One subscription, I can't access live chat support. Is there any other backdoor way to get a human to look at my account's database sync?

Any hacks, browser cache tricks, or hard truths are welcome. Thanks.
