After upgrade multi-currency issues

After upgrading from ver 13 (not sure exact) to latest (15.4.54), all my multi-currency transfers are wrong, throwing off all my bank balances. Seems that it switched all my transactions to use what was previously the target account value to the originating value.

Something like previously was

USD -50 to IDR +500.000

now shows as

USD -500.000 to IDR 500.000.000.000

Wish I would have saved old installer to revert, but only fix I can see now is to go back and fix all the transfer transactions.

Any other easier way?

Can you send your accounting file to support@manager.io ? Also mention what exactly to look at. What you expect to see and what you see instead. That’s usually enough to find the issue.

Thanks for the quick reply. I have sent the file and info to you.
