Vocabulary sync

I started using the app yesterday and when I go on the site from my computer and the saved vocabs are not synced.
Is this how free accounts word and it’ll be fixed after I go premium or do I have to import manually or there’s an option unchecked?

What exactly isn’t synched? Are you sure that you are logged into the same account on both devices?

the words I add using android app from 2 different devices don’t show on browser but the words I add using browser do show on other devices
so the only mutual words that show are the ones I add from browser
and yes I’m logged into the same account on all of the devices I’m using

Please try to logout/login back on the app version and let me know if that helps.
