Properly learning Albanian - need help

Hi everyone - As someone who was born and grew up in the swiss diaspora, I‘d like to take the time and properly learn our language. I‘m not really sure, how it is in other diasporas, but atleast in switzerland, you‘re not really well exposed to our language, not even with our people (with the exception family and I can‘t spend all the time with them) and over 95% (I‘d say) it‘s mostly our people from Kosovo or Macedonia and they often prefer to speak in german. Therefore, can anyone tell me good ways to learn Albanian? I want to extend my vocabulary + being properly able to write in standard Albanian. I have no issues into engaging into conversations, it‘s rather that I have troubles understanding some words in sentences.
