Keyboard number input not working

If I open a new page, I can type a single number and it will input a chord. After that it doesn’t let me input anything in either the chords or the melody section. If I open a new page and type 123, it will input a one chord but not a two or a three. This makes the app completely unusable.

This used to work and now it doesn’t, haven’t use the app in a few weeks
if I open it in incognito mode in Chrome it works just fine, I’ve tried a million times and I can’t get it to work outside of incognito.

@NatalieHooper, not sure what the difference would be between regular and incognito modes, do any of the other shortcuts work? Do you see this same behavior on Safari or Firefox?
