The changelog released today for Play Store 44.1 says this “Share apps feature on Google Play will be retiring.”
At the time, Google billed this feature as a way to send and receive Android apps without Wi-Fi or cellular connectivity. Peer-to-peer sharing can also conserve data and is ideal for places with slow networks
You can still use Files by Google to share Android applications in a similar manner. Under Categories, go to “Apps” and then the overflow menu for what you want to “Share.”
Although I never knew about or used this feature, it does seem like it could have been useful for some people before Google killed it
Has anyone tried PairDrop?
Never tried it, but LocalSend works great. Cross platform, just need to to on the same WiFi network, hotspot works fine and network does not need internet connection.
