Hello @luu d

Thanks for posting in the Community!

Hopefully you received a few notices from us in the past few months informing you that due to Apple’s policies the iOS app will only be available to those on a Team or Enterprise account.

However you can continue using Lucid products by logging into lucid.app on your device.

We're sorry for the inconvenience! Please let us know if you have any questions on the above!

I would try to log out of all devises shut the device down they're start the device and e log in or try changing your password before attempting a 2nd time. it's a cloud-based web app and sometimes this happens. if this doesn't work contact customer support.
