Code when changing clock face

[Arame.R]

Does anyone knows where and why it is asking me to enter a code when changing face clock?

Hi @Arame.R - Some of the third party clock face developers sell multi packs. If you want to switch to another of those faces ... or if you switch to an unrelated clock face and are now trying to go back to your original, they ask for a code they should have received from them.

Otherwise, just pick a face that is not asking for a code.

Thank you for your reply. I ended up using one of Fitbit's face clock. I did not realize the other ones were not free.

I received that code in my phone text messages. I'm looking for the code that starts with a S.
