No, right now you can’t see an active Clue Plus app subscription in your Clue account on helloclue.com.
If you sign up for Clue Plus on helloclue.com while already having an active Clue Plus app subscription, your active one will not be terminated. This means you might end up with two active subscriptions at the same time (one via helloclue.com and one via the app).
It’s best to wait until your Apple App Store or Google Play Store subscription has expired, and then re-subscribe to Clue Plus via the website.
