Can I go to Switzerland while the Covid Certificate App is processing?

I'm traveling to Switzerland in a few days. My hotel says they check for covid vaccinations using the Swiss covid app. I have a vaccination from the US, but it takes up to five days for it to process into app.

Does this mean I have to cancel my hotel? Or is there some way I can get a valid EU or Swiss covid certificate sooner?

Edit: I'm going to Bern canton. I have a paper CDC vaccination card (with booster). I flying in to Zurich from Denmark, but am a US citizen. The hotel says it is under 2G rules.

I called the Swiss Covid hotline, and they said I might be able to get some sort of certificate in the airport? But they weren't completely sure, and didn't know if it would be open on Jan 1st.

Not really an answer but a few data points:

Last time I tried (September 2021) to convert a US based vaccine certification (CDC card, smart health card, PDF doc) I failed. Nothing online I could find would accept any of my US credentials. They did accept my credentials at the airport on arrival for entry.

I was able to get an EU Covid pass in Germany, but since then Germany has stopped doing this, since the CDC card is just to easy to forge and you can buy them online in bulk.
