TLDR; Let’s Encrypt, the free SSL provider, has announced it’ll stop issuing and allow the intermediate SSL certificate to expire during 2024*, which enabled continued support for Android devices <= 7.0.
This means if your website relies on Let’s Encrypt to supply SSL that as of June 2024 any visiting customers on Android <= 7.0 will fail to connect.
For many of us, Android 7.0 or older represents much less than 5% of all visitors, for Pipe Ten and Purely, this is less than 1% (closer to 0.3%) in the last 12 months, and the event will pass largely unnoticed.
For other more mobile heavy user-bases, check your user-agent logs and consider assisting your customers in migrating to newer Android versions or alternate browsers like Firefox Mobile, which can support alternate intermediates.
* This date was already extended in 2021 to beyond its expected lifetime after community feedback.
