Am I the only one to have the following problem :
I am fully vaccinated in France and have the typical EU vaccination form with QR code. Every time I finalize the Spanish QR code application 48hrs before flight, I have an error message when I upload my certificate (choosing the option "EU covid vaccine certificate"). It says something like "your file is not an EU covid vaccine certificate". So I always end up choosing the option "others" where I have to enter the details of which vaccine I received, when and where but without uploading the certificate. I never have problem when they scan the QR code arriving in Spain, but this is just weird.
