Russian letters are not displayed

Hi! Im not quite sure, but after last watch (?) or Facer (?) update smth happened: russian letters are not displayed on a screen, just empty lines. Any idea why and/or how to fix it? Yhanks in advance!!! PS. Huawei Watch 2 Classic

I had a date widget on my watchface, but suddenly, all russian letters are disappeared. I thought there’s something wrong with date widget itself, but when i’ve tried to put a label with custom text, this text is also doesn’t show on actual watch (it’s shown only in preview). Sony Smartwatch 3.

Mb someone knows?)
