Q: I only see sticker numbers up to NNN. Shouldn't it show 539 stickers?
A: This is a known bug in version 1.0.3 if the first time initialisation was not completed correctly. Please allow the initialisation to finish upon first launch, to prevent any side effects, do not even let the screen lock. Fix is available in v1.0.4 or through complete re-installation (with data loss).
