We are. The only possible fix we could come up with was only loading embeds on demand, reducing the resource load on the mobile browser. I believe this was ready to be deployed last week, but we are in a publishing freeze for something this extensive until some of the news cycle dies down. I'll post back here when the fix is out.
seems like a pretty disappointing fix honestly, if it will be something like i have to click on every embed to load it individually. but i guess that is better than what is happening now.
