Don't use Google and APKPure misbehaves - how do I update apps?

I have RedMi 3s (Android 6.0.1) phone. Also, I don't like Google, don't use their email and don't work with a Google account - so I don't use the Google Play Store. For a few years, I have been using the APK Pure app to update all of my other apps. But - a while ago (perhaps early this year?) - somehow, it kind of stopped working. That is, it recognizes the apps that need updates, but never manages to actually get the updates going. So what I'm looking for is another method/venue/app for routinely updating my apps. Preferably - one in which I don't have to actually press "INSTALL" for every single update, but I'm willing to live with that. Alternatively, if I could someone overcome my APK Pure issue, that would be good too. Any ideas? Note: Manually updating individual apps works fine.
