Spanish health form

Anyone having problems with the Spanish health form app. Opened it this morning on my Android phone. It says Update to continue. I click on update and it sends me to the Playstore page to install the app which is already installed. My phone automatically updates so I am at a loss.
Also uninstalled and installed again. Switched phone off made no difference.

You can just try doing it on the website: https://www.spth.gob.es/

Thanks yes I have. Annoying the app doesn't work though.

The app is doing the same on my phone.

www.spth.gob.es it works on the website. What is the point of an app if it doesn't work?

My wife used the app and saved it ready for the return trip okay. But the last two days its been a bit iffy. It said app update needed and sometimes it froze and sometimes it went to the playstore for the update, but on opening the app it again said update needed. We completely uninstalled it and started from scratch in the playstore. Still playing up but today it is fine, so there must have been something going on as we tried two different phones. Hopefully all will be good when my wife applies for the QR code on the return. Its fine on the PC, so maybe a direct download if a problem on mobiles would be to download the app via a Chrome browser direct as all mobiles have that. As I think the before comments mean that way.

Yes you are right. The app is working now. Good to know the form can be downloaded from the website as a back up.
