Hi Kevin!

Definitely keeping an eye on mobile Safari issues, thanks :)

Regarding xzing, luckily we had a limited device range for which the app had to work, but our tests were definitely positive on iPhones and the latest Galaxy phones (at the time I believe it was Galaxy 7/8).

If this was released to a wider public we would have probably considered a solution with commercial support , but only charging unit operators use the app :)
