Good afternoon to everybody!
I have a problem with an addition and subtraction formula in my app, when I test it on the web where I develop the app everything works correctly (photo1) but when I test it on my cell phone (android) the formula addition does not work correctly. I have noticed is that it does not recognize the decimal point in the values that I add (photo2 and photo 3), however, on the web all the values entered with decimal are addition correctly.
Photo 1 (app from the web):

Photo 2 (app from my telephone):

Photo 3 (app from my telephone):

Please, if someone can help me with this, I already tried the text formulas, ###. 00, change region es-ES but it doesn't work.
The app would be used in Peru - South America, so I don't know if it's a cell phone configuration issue.
Thanks!
