Nope, pretty normal. You’ll find that you’ll need frontends and proxies for tons of things. For example Instagram hasn’t ever worked for me with a VPN. I no longer have an account anyway, but for the times someone sends me a link I’ve had to find sites that let you view the content without actually visiting Instagram. Same with reddit, reddit frontends are very good these days (I’d recommend any Redlib instance). Also, sometimes a specific VPN server is IP blocked and you can just connect to a different server to view a web site that blocked you initially. It is a fair amount of work, but honestly its helped me slow down my consumption of random bullshit anyway haha. I use ProtonVPN and pay for premium.
Agreed… depending on Google to implement or fix very specific features is just shouting into the void. Use a trusted 3rd party app like Bitwarden, as you mentioned
