Can you click on the File > Open menu item or is it disabled ?

Yes you can do it by creating a new currency in the list of currencies. Set its change rate to 1 and decimal numbers to 0.
You can then go in the report editing screen and select the new currency in the currency field.

If your QIF files happened to be located on iCloud Drive for example, you could also open them in Files app and click on the action button to open them in iCompta 6.

Yes, you just have to select the QIF files in the attachments of your email, click on the action button and finally select "Open in iCompta 6".

I'll take a look at it however do you know that you can simply email yourself the qif files ? It should be quicker than using the embedded web server.

I used your system settings on my computer but I can't manage to reproduce it : Do you have latest macOS and iOS versions or older ones ?

Thanks for the information, can you also post a screenshot of your Language & Region settings ?

Thanks for the screenshot, I think it's a problem with the specific bold font. Does it display correctly in the amount field in the right editing panel ?

Can you post a screenshot ? Thanks

Yes, it's a bit of a workaround, but you can create a splits report and change the "Group by" field to just "Project" or "Tax category". This way you'll see all entries.
