Online resources for learning German (besides Duolingo)?

Hello everyone! I've been learning German for a while now and I'm really enjoying it. I've been using Duolingo, which is a great app, but I'd like to find some other online resources to improve my skills. Do you know of any good websites, apps, podcasts, or YouTube channels for learning German? I'm interested in everything from grammar and vocabulary to pronunciation and listening comprehension (My German level is not very high…just A1/A2)
