docs.nativebase.io has many errors in console of Chrome

[totanvix]

I get many errors in my console when reading the documentation.

The first time I visit the site, I got Uncaught (in promise) Error: 3000ms timeout exceeded.
.

The second time I got _app-1e2a320361e2cafc.js:1 EventEmitter.removeListener('function(){l(o)&&u({inst:o})}', ...): Method has been deprecated. Please instead use remove() on the subscription returned by EventEmitter.addListener, when I switch between document pages many times.
.

I used incognito tab and turned off all extensions, the errors persisted.

Bugs that slow down the page.
