I wanted to propose a simple workaround to an issue, but was blocked. This issue is described in
The thread is closed, suggesting upvoting or commenting in this link returning a "Permission problem": https://community.quicken.com/discussion/7914352/add-an-unlink-transfer-option-to-the-right-click-register-menu#latest
Can you help the community by updating the discussion?
Here is how I address the issue:
1) If the link was just created, I just “Edit > Undo Transaction” (Command-Z on a Mac)
2) If the link is older, I just right-click “Duplicate Transaction”. I then set the original transaction to “Uncategorized” and accept the warning that the other end will be deleted. I then go to where the other end was, where I can right-click on the duplicate to also set it to “Uncategorized”, again accepting the warning. I can then recategorize both transactions.
