Android app shortcut changes not saving

Hi guys,

I use logseq on my Android tablet. The tab key on their official keyboard, according to the customer service of the brand, follows a different protocol and thus triggers a bit of different functions. Rather than indents, it only creates a big space. Therefore I tried adding Ctrl + Tab as the new shortcut for indenting. It works until logseq is exited and restarted. Then I have to add the shortcut again.

Just wondering if anyone knows how to keep the shortcut changes.

Thank you,
