Versa 2 will not hold Achu app

[Chasincows]

so it said try a fitbit app...I really wanted achu but it kept going off and saying error??

So I gave in and picked a clockface and it came on but just like ACHU it reverts back to 

another black one in 10 secs how do I get rid of the first one so it just shows the one I want

without tapping it twice

Welcome to the Fitbit Community, @Chasincows. I am sorry for the delayed response. 

I appreciate your participation in the Forums and sharing the issue you're experiencing with the Achu clock face. Many clock faces require access to certain stats or other information. Note that turning off any of these permissions might cause the clock face to stop functioning. I recommend checking this help article for more information: How do I change the clock face on my Fitbit device?

You can find the steps to remove the app and other useful information in this help article: How do I install and manage apps on my Fitbit watch?

Feel free to reach out if you have any questions.
