All users receive 941 error message when trying to install my app from Google Play Store

view story

http://stackoverflow.com – I just published an app on Google Play. Whenever someone tries to install the app he first receives the error message 941 and the app can't be downloaded. When trying again it is possible to install the app. From what I found on the web this error message can be avoided by clearing the cache for the play store app. But since this is appearing on every device it seems to be a bug on Google Play store connected to my app? I hope there is any way to solve this issue so the users don't get frustrated when trying to install the app (HowTos)
