Yandex.Maps (https://yandex.com/maps) never worked in Otter correctly. No zooming, no dragging, no street panorams. Windows 7 x64.
@Freeman, have you tried masking as Chrome or something else?
@Emdek, tried to mask as Chrome, all worked! I'm surprised. Thanks!
@Freeman, well, I'm not, it's 2017 and a lot of sites still check for UA instead of doing feature detection...
