Default Play Store country restrictions

Hey guys! To start off, yes, I searched the forums and yes, I tried Google as well.

My problem is that I live in Austria, my Google account is set to Austria, I have an Austrian phone number... Yet when I try to download the mobile banking app of an Austrian bank in the play store, it shows it as not available in my country. Iīve tried all the methods like market enabler, vpnīs and like to make it work but without success. Also, most of these articles were written more than a year ago, so probably they are not really up to date with all the changes. So, could any of you give me an advice on how to download the app?

Thank you for your replies!
