Thank you for the prompt response!
I’ve already tried reinstalling shopify-cli and it seems that everything is up to date. In addition, the app I’ve created was through the provided templates, and seems to be working fine. The main issue from what I can tell is that the cli isn’t able to create a tunnel despite it saying so. On my ngrok account, it doesn’t display a tunnel when executing the ‘shopify app serve’ command, which is in contrast to when I create a tunnel directly through ngrok.exe.
As things stand, I am incredibly unfamiliar with tunnels and have no clue how to complete the process manually. So, if it were possible to do so, are there any online resources which could explain how?
