PWA: I agree, but the look and feel of native is just better. Additionally I‘m also planning widgets and these are just easier to implement if the rest is already native.
Privacy Policy: I‘m using an external service that I‘m paying for monthly to host that. With the payment, there shouldn‘t be any ads, but looks like they‘re still shown. Will definitely spin up something on my own on Cloudflare pages or similar, thanks for the heads up!
