I have a Carpe Iter as well and I can confirm the same behaviour.
Even with the Webview Version installed from the link above.
The Carpe Iter has a modified Android Version 9 installed on it.
Can I provide any more info to solve the issue?
What could we ask the manufacturer to solve this?
Ask him to update the Webview component or to update the Android version?
The latter is probably very unlikely
But I would love to have the new Kurviger Version on my Carpe Iter!
I do have the same issue with a Carpe Iter Pad running Android 9.
No Add blocker, Chrome is up to date and all other apps running without any issues.
The old Kurviger Pro app also worked fine.
I’m having the same issue on an Samsung Active Tab 2 that I just purchased, it is running Android 9 and the apps are all up to date. I think it is very similar to the Carpe Iter tablet. I get the same error on other websites, like trying to access taskernet.
Samsung usually has an updatable Webview, I would be surprised if it would be the same issue, I would recommend to first try other options, for example:
