So, I've heard about XManager for a little while and just finally decided to try it, and...
So just level with me, is this thing an advertising scam? When I tap on a version and choose download, an ad appears, I wait for it's timer to finish, close it and... Nothing happens. It never downloads anything, just serves ad after ad.
Edit: So, after disabling ads and trying again several more times, I was able to download and install.
It's not a scam. It just has issues compiling the APK on certain phones, like Xiaomi. They have a Telegram group to download precompiled APKs without the need for xManager.
