Tik Tok shop disconnected from shopify app

seems like theres a few of us having this issue support was no help whatsoever as always told me to uninstall the app and t=reinstall but im scared to as i have orders to be fulfilled etc and not sure if this would destroy them was also told to go to tik tok and ask for help but to me its a shopify issue as its a acess token getting sick of the problems with this might just call it quits now
