I am new to this software - I have uploaded my logo but on the invoice it is too small.
When I have tried to upload a new one - it does NOT seem to replace the older version.
Is there a simple way to remove the old one and upload a new one.
It should replace your old logo. Perhaps there is something wrong with the format of new logo. Could you send your new logo to support@manager.io so we can reproduce this issue ourselves?
