Gemini Transaction History

Hello I have contacted Koinly support multiple times and received zero help – I have a pro plan for four years. I have tried uploading the excel file that Gemini sent me, but it keeps saying the file failed to upload and I need to reformat it. Has anyone else had similar issues when uploading trade/transaction history for Gemini and have any advice?

Thank you in advance.

Have you tried the sync using the API? That is how I do mine and works great.

I don’t have access to the account anymore otherwise I would have synced the API in the first place
