@lemmy.mloutside of sandboxing/limiting android auto via grapheneos good luck.
if you just want audio & your car doesnt support Bluetooth you could use an adapter to take it from Bluetooth to 3.5 aux. if your car is so fancy it doesn't have aux input you can get a Bluetooth to FM radio adapter that will take over one the channels in your car as well.
have you considered using alternatives front ends for some of the major social platforms?
I use libreddit/redlib to browse reddit. you can run an instance locally or connect to remote ones. this way your IP isn't logged by reddit in the first place & no JavaScript is required to be run for the website to function properly.
there is even an extension called libredirect which can automatically swap clicked reddit (& other platforms) links to the same page on public frontends, which removes the hasstle of manually changing the URL.
unfortunately the blocking of servers is a perpetual battle that plauges almost any publicly listed proxy (vpns, tor, etc). the only way I have found around it is using lesser known/blocked VPNs or residential proxies. both of which probably have subpar data privacy policies, if they even follow them at all.
althought it likely won't help your captcha troubles, I would like to give a huge +1 to mullvad. have been a happy customer for years. in compsrison to proton as a company they have a much more direct/benifitial effect on the web & furthuring users privacy online in my eyes.
scrambled exif is really practical & easy to use. it has been a player for a while now where as metadata remover seems newer & possibly less trustworthy/vetted because of it.
it also doesnt seem to add much new functionality from scrambled exif besides viewing data in app.
I personally use image toolbox which allows you to select what specific exif tags you would like to remove. however, I wouldnt put any more trust in its accuracy or comprehensiveness than any other adjacent app as they realistically all probably work very similarly.
if its imperitive you don't leak any exif data I would recommend checking that in an external & more trusted app anyway. something like aves or a similar gallery that will lay out all all metadata tied to an image.
quite sure this isn't implemented at the moment unfortunately. I have a similar setup & similar issue but haven't been able to resolve it.
it may be possibly to set up some kind of dual setup using unified push to receive notifications on both profiles, but I haven't been able to find a tool to do so & am doubtful after looking at the way unified push works.
unified push works as a stand in for gms on devices without it. it runs in the background & receive the wakeup pings for the apps (in this case simplex) so you only need one websocket open instead of a different background service for each app. hugely reduces battery use.
