Wrong Numeric Format from SharePoint Calculated field results in 0 with SUM()?

[Finnair]

I have an Amount Field in SharePoint which is a Calculated Field and the format is Number (automatic number of decimals).

When I refer to this field on PowerApps Canvas App Form and try to sum it with SUM(Amount), the result is 0 (although it shouldn't be).

It worked once but somehow stopped although I haven't changed anything. If I bring the field and some value within it to PowerApps Form, the form is 31500.00000

In my country we use comma as separator. I wonder, if the dot is the cause?

This is very frustrating since I don't know where is the fault: In SharePoint Column or PowerApps.

This was solved by changing back to Edge. I accidentally continued my app with FF today morning whic made my calculations a mess. But good to know fro the future!
