The android version is downloading as a .zip again...
Viewing post in WEEKLY RELEASE - v0.18.5! comments
Yeah, it’s kinda out of Arc’s control.
Why would he intentionally put the APK inside a zip file?
But you can either extract the zip with a file manager to get the apk inside. Or use the Patreon/Subscribestar links on the public posts.
The public release on Pat/SS is the same as the one posted here on itch.
