Doesn’t work with other EU+ certificates

Seems to only work on Czech certificates. Swiss and other Schengen and EU+ country certificates don’t work.

Nepozná bulharský QR kód

Funguje s bulharským kódem k druhé dávce Pfizer, ale ne s bulharským kódem k Johnson&Johnson. (Kód je dle oficiálního bulharského webu i ekvivalentní dánské aplikace platný.)
