I'm super impressed with the dev's progress too, but I had to uninstall when I saw that Voyager was dropping a line item into my chrome browsing history with every post I tapped on.
Nothing sinister about my activity, but it seems like a bit of a privacy faux pas for me, so I uninstalled and moved to Connect instead. Might be back if the history thing goes away, as it's an excellent app otherwise.
This is an Android thing. It's just the way PWAs on Android work unfortunately, when PWAs change URLs they get logged to the browser history. I think it's a poor behavior though, and I think Apple's approach is better.
Ive heard rumblings of changing this behavior on Android though.
