Cannot connect facebook account to facebook app

[ShyBanana]

Hi guys,

I tried to follow the steps to set up an Instagram and Facebook store, however, I'm stuck at the first step:

An error message shows up after clicking the connect button, saying the link is expired. We are located in Australia and according to meta ads, we are eligible to have Instagram stores in Australia. 

Has anyone else experienced this issue before or has any solutions?

Thanks!
