PowerApps uses the deivce's localization to display dates and number formats. Even if the SPO-list has the regional setting "de-CH", in PowerApps it is not available. So it uses "de" or "de-DE" which is slightly different to "de-CH". While "de" is using a comma as decimal separator, Swiss people are accustomed to use a dot.
Has anyone another idea than to build a replace function to solve it?
Or could you guys from Microsoft add the Swiss language settings?
