The file “default.store” couldn’t be opened

I installed grocy with docker. The web ui works fine, the login in the app works fine but every request generates an error:

I had the same error (Issue already closed). You need to update to iOS 26.2 or to iPadOS 26.3 (26.3 could still be in beta)

[thelfensdrfer]

Good point, didn't include it in the issue report. By I am already on iOS 26.2 on my iPhone and iPad. Both devices show the same error.

[isopentade]

Then try updating to the beta (26.3), that is what fixed it for my iPad. I don't know about the iPhone, though.

[thelfensdrfer]

Thanks for the tip, but both devices are in production use, and I just wanted to test the app. I will just wait for an app update or iOS 26.3, whichever comes first. Sadly, I have absolutely zero knowledge in iOS development; otherwise, I would have created a PR.
