Yes there is an issue that is preventing you from continuing to run. It starts after toggle but stops quickly. When the key is bound correctly you can hold it down. They hope to release a hotfix for it soon.

However, I’m also experiencing what you mentioned. After I tried tinkering with my key bindings on Xbox, I now lose the sprint toggle binding completely after restarting. I have not heard them mention this detail specifically but I hope the patch address this too.
