I had to change the password for my TP link kasa account. When I attempt to open TP Link in the ‘linked services’ menu it opens then closes right away - I am unable to enter my changed password via the app.
I’d prefer not to delete then re-add all my automations, etc.
I believe you do not need to update the password. If everything still works, I would not worry about it. I have changed a password on one of my linked services twice (not tp-link kasa) in the past couple of weeks and never had to update it in tHe ST app. It still works fine.
Have you tried force quitting the app or signing out/signing in to see if that allows you to open the linked service? Doubt it will help but worth trying.
