Hi @thesunilyadav, just wondering if you might be interested in taking a look at this PR given that you reported the original issue (#409), and had helped out during the issue discussions?

It's working for us in production, by modifying our app's composer.json to use this branch:

Also @Kyon147 I'd really appreciate your eyes on this when you can.

Thanks

Hey @thejamescollins

Thanks for the PR, I'll take a look this week and spin it up on a new app so I can check the flow works for the old way and new way.

p.s great work btw 🙏 i'll give it a proper code review shortly.

Looks good, I just need to spin up a test to go through and check the flow for both.

@thejamescollins are you also able to update the wiki to include your new logic?

Either we add to https://github.com/Kyon147/laravel-shopify/wiki/Authentication-Process or we create a new page about the managed installation itself. Happy for you to decide which place is best for it.

Hi @thejamescollins,
Thank you very much for your contribution! I'll take a deeper look into the installation/uninstallation process over the weekend to ensure everything works smoothly without any breaking issues.

Hey @thejamescollins

This is looking good on my end, I just want to re-test it again today but will merge it in the week 🙏

[Kyon147]

This is good for release @thejamescollins will sort a new release out tomorrow.

Will bump up a minor version as it is a backwards compatible change.
