whenever I try to upload my project I see this message in the console and have no idea what is causing it.
Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.
and this is the link that is trying to access a frame in my app
https://s-usc1c-nss-134.firebaseio.com/.lp?dframe=t&id=1311060&pw=Amzlpqc8eF&ns=myapp
I’m a bit worried.
