NRC app in watch not syncing with iPhone

Hi!

I’ve been having the bad experience of my watch not working (synchronizing) with the iPhone when using the NRC (Nike Run Club) App.

I’ve uninstalled it from the watch, from the iPhone, un-synchronized both watch and phone, and nothing seems to work.

Please help! I have an iPhone 8 and an apple Watch S3. I’ve also written like 5 times on the NRC comment section in the app store and there is no feedback.

I run almost every day so this is important to me, and I wouldn’t want to have to change to another app, bc I would loose all my running history.

Thank you! 🤞🏻
