Cannot sign in through application

That link is not working. I found geogebra classic beta version on playstore but it shows my device is incompatible

not working

what happens exactly?

I gets some error messages on opening the link

I have created a bug report which contains system log and about the system. Will it be helpful to developer team?

Please just say which browser and Android version that is

I'm using Google Chrome. More details:

Thanks. Now I've joined the beta version and I could sign in. I'm wondering why geogebra classic is not available for Android phone. It is such a powerful tool. In our syllabus we have to use it for studying math.

[Edit]:

Now, how can I access my old files from the beta version which I created in the stable version and saved in the device locally?
