Logseq 0.10.9 on iOS ipad : bullet lost

strange behavior since I updated logseq ( mac and iOS)

On my laptop: expected behavior
On my iPad: bullets disappear

Even worse: when you click on enter, the text is added below , not as a bullet, but as if I clicked shift enter …

If I go back on my mac: iOS updated text seen without bullet

I disabled all plugins, css customizations, reindex each time I switched device, test with a new graph … no chance

Hope this will be fixed

Addendum: issue happens only with ipad on-screen keyboard.
Works as expected with extended keyboard ( logitech)
