Listening to songs, while reading the lyrics and looking up unknown vocabulary. Collecting and revising those words with a tool like anki. Watching movies with, - or if you already know the movies without subtitles (like Disney movies you watched regularly as a child). Listening to local radio stations. It doesn't matter if you don't understand anything in the beginning, it's for getting used to the overall melody and flow of the language, which compensates for the lack of in-person immersion. Side by side textbooks, or buying your favourite books in the language and reading them side by side, should be good to improve your reading skills.
