As written in the title, I just downloaded an official app from APK Mirror, it has 2 files apk and apkm and since the apk version didn't work, I tried to download the second one i.e. the apkm one. I don't know how to install it.
So I googled and found this. Yes, I'm aware of the article that says converting APKM to APKS, it doesn't matter because I have a tool to convert APKS to APK
I don't know if it's a scam or not but the app that's called unapkm, after installing it, it doesn't have the "open" option and the app isn't appeared on the screen or perhaps I just don't know how to use it. Anyway, is there any chance to convert the apkm to apk so I can install it normally from my phone?
