Restore to previous good working version

Describe the problem:
I had a problem of corruption due to mistakenly uploading the wrong file into a exchange wallet and had to rebuild and start from scratch but now I have many issues including large cost basis errors which I cant modify or fix.

Which exchange/wallet is this regarding?

Binance
How did you import data into this wallet?
API and CSV

What have you tried to fix this so far?
I had to re-synch and re-add what files I could

I wanted to know if its possible restore back to a previous working profile ?
since rebuilding I have a lot of problems - errors which I cant reconcile.
Some rewards or interests dont get down loaded via API but some other cost basis issues have arisen which I dont know how to fix.

Hello,

Unfortunately, we don’t have that feature. Koinly has no KYC and doesn’t store your private data, so once you’ve deleted something or re-synced it, we only have that data, nothing else. Also, Binance has made some changes to their APIs so that could also be an issue. I suggest also you use either CSV or API, using both can cause problems and duplicates on your wallet.

If you’re facing a lot of trouble, please consider contacting support directly with a ticket so we can check your account and assist you better.

Kind regards,

Anakin
