Proof of vaccination is required via the ArriveCAN app at least 72 hours before boarding your flight to Canada. Instructions say you have to upload a file for each vaccine. Great, but the EU digital Covid vaccination certificate - at least those produced in Germany - are printed out on a large piece of paper, and you're meant to fold it twice for portability.

Also good - but when you lay it out flat to take a photo of it, half the information is upside-down.

Is this going to pose a problem? I know you're supposed to take all physical copies of proof of vaccination with you anyway.
