Music Stand don’t work at Samsung T560

I have a tablet Samsung T560 with Android 7.1.2.
I tried to install the Music Stand app but appears the message: it’s not compatible with this tablet.
The app Planning is running well in my Tablet.
Could you help me in this issue?

Music Stand requires Android 8.1 or higher. You won't be able to download the mobile app but you can use the web version of Music Stand, found through the Planning website.

Ok
Thank you for the information
O will try to download other Android version
