Huawei & MySugr

I have a Huawei mobile phone and I use the Accu-Chek Instant glucometer.

A few years ago the MySugr app worked perfectly but now, it doesn't work. It does not auto sync my readings etc.

I have asked MySugr for help but , yea, to no avail.

Has anyone experienced issues using a Huawei phone and this app?

If anyone has alternative suggestions, I'd welcome them.

Thank you
