At this time, you cannot transfer a symbol from one account to another. A great work around is downloading your symbol and uploading it to your other account. To do so:
- Open the symbol you want to copy over
- Right click on the symbol and select “download content as JSON”.
- Create a new page in your other account.
- Navigate to the new page and right click anywhere in the editor window. A menu should pop up with different options. Select “upload .builder.json file.”
