Calling the link function on already linked accounts

In my UI, when a user switches accounts I ask them if they want to link these. However I check if the accounts are already linked beforehand and if they are, I don’t show the prompt.
If two accounts are already linked, should I still call the link function? Doing this, updates the ethAddress collumn in the Users table, I’m not sure if this is required.


You should not need to link the accounts that are already linked.
It should only be done “once”, when a user switches to an account that is not already linked.
