There shouldn't be any serious compatibility problems between v0.3.3 and v0.3.4. Unless you have a way older version in which case the game should automatically clean up your save data due to incompatibility.

I have been cleaning my tablet with android 9 from some files to see if that the problem. Once I had a install problem because its need near 4GB free space to install the update. Sounds like that is normal in some apps depends of the size. Even if the app isn't big. When that happen it just don't install and not even say why.
I end deleting all my snapshots by accident luck I had a backup in Onedrive. To be true I deleted those in the Onedrive and the synchronisation deleted it from my tablet but I got back from the Onedrive.
Thank you for the attention.
