Hi Rose,
I disabled W3 Total Cache – it resolved the issue on both Mobile and Desktop.
I tested several scenarios. Browser cache settings – not related to the issue.
Page cache – when disabled – issue resolved on Desktop. Still present on Mobile. When I enabled it again, the issue didn’t come back on Desktop
Then I disabled Minify – it resolved issue with Mobile Menu – but it is coming back when I enable it again.
I am now afraid that disabling it will impact speed of my website.
