Bugs in Docs on Chromebook -- docs update?

Since about a week ago, PaperPile has been acting weird on my Chromebook. First, the shortcut Alt+Shift+P now brings up the ‘explore’ menu as well as the PP citation search. The explore menu interferes and has to be closed before PP can be used. Second, having added a citation, I no longer have an ‘edit’ option, only the option to change or remove a citation.

This problem has mysteriously disappeared.
