First my daughter had an Echo Show and registered it with her Amazon Prime account. Then I got one and registered it with her account. Later I got my own account and re-set my Echo Show to be on my own account. I have re-set it several times. Nevertheless, my daughter (in another state) still sees my calendar on her Echo Show! On my Alexa App it shows just my gmail account as being connected. How can I disconnect my calendar from her Echo Show?
