Cannot paint definite blanks (yellow) on Android tablet

[fkuipers]

Hi,
Ever since the day before yesterday I am unable to play Numbergrids on my Android tabled, because the yellow blocks will not appear. I already restarted the tablet but that doesn't change a thing.
Does anyone else have that problem? Or ever had and know the solution?
Thanks in advance for your reactions
Fred

Hi all,
We found the cause: in one way or another, the browser's check box "Desktop site" had been ticked.
After unticking it, everything works fine again.
