@Cécile_Echard - I have tried now and even the Facebook version under Firefox/Linux has a target of 35, so we have as of now:
- Android (Beta): fixed
- Facebook: fixed
- Gameroom: not fixed
- Windows 10: unknown
Windows 10 is peculiar, but you're using Windows 7 - are you connecting via Facebook or other game portals? Perhaps you might try clearing the cache of your browser and see whether AlphaBetty gets reloaded?
