Issue with closing braces

Dear all,

I have an issue when typing closing braces in any notebook on Mathematica Online. Whatever the format of the cell (e.g. input or text), when I want to write a closing brace }, I type AltGr+= (French keyboard) and I obtained a box (confer file attached). The only work around that I found is to copy-paste closing braces from an external text file.

Any help would be greatly appreciated.

Regards,
Xavier

Idem : A simple “Table[i^2,{i,1,10}]” can’t be evaluated because of the fandango of the “}” triggering an alpha-like empty field !
