This has me baffled. My later iPad and iPhone are using iOS version 13.3.1. The Blink version (which is up to date) is version 220.127.116.11.
But I’ve just installed it on my old iPad, which is limited to iOS version 12.4.5, and to my surprise found a different, superior interface. On checking About Blink, I see it is version 18.104.22.168.
What’s going on here please? Version 6 is superior for me because it gives quicker access to sharing with Dropbox. In contrast, that’s a cumbersome procedure with version 22.214.171.124.
