I’ve been working with metahumans for a long time now, and happily using the LiveLink Face app. But since one week or so my connection with my phone and unreal keeps cutting out every 30 seconds to a minute or so. I’ve checked everything, my phone settings, my wifi router, my connection via my phone. The only difference i can think of is that maybe my IPhone secretly updated and screwed with the app, or the app itself changed.
The problem is not with unreal or with the PC because ive tried it on three different laptops, with unreal engine versions 4.26/4.27/5.1UE/5.0.1 and all encountered the same problem: Poor or cutting out connection with my phone.
Is there anyone with the same issue and/or knows how to resolve this?
Here’s a video of the reoccuring issue:

For the people having this same issue, it was indeed an issue with the latest update of the IOS15.
IOS15 has a new function in their wifi settings called “low data mode” and “Limit IP Adress Tracking”. Both of these will intercept the transfer of data for facetracking and will result in incredibly laggy or even cutting out facial movements.
I’ve reset all settings in my IPhone, and while I was at it just erased all content and started with a clean slate. I saw that when I put my phone to factory settings it will automatically turn on “Limit IP Adress Tracking” and instantly saw the lagging again. When I turned this off it finally went working back to normal.
Hope this helps some people!

I was really hoping that this would work. I found Low Data Mode, but it was already disabled. I had to upgrade to the new ios and found the Limit IP Address Tracking which wasn’t there before. I disabled it and am still getting the lag/drop problem. I reset my router and it still is lagging the same. Still open for a fix. Thanks!
Figured it out. I had added 2 ip addresses in the Live Link Face app on my phone. 1 for each computer I was using. Just had to delete the one I wasn’t using and now it is working normally!
