Hi @Deafveloper, this PR includes many commits from other contributors. :) I believe this happened because you've based your commit on a different branch instead of the dev-sign branch.

Let me check if simply changing the target branch to main branch will fix the issue. (I don't mind if we use the main branch directly.) If you're not too familiar with Git/GitHub branch concept, the above comment might be a bit confusing. But don't worry, I'll help you through it!

[seokho-son]

Yes, the base branch of your local/feature is main. You can see this PR includes your commits only.

So, we either need to change the target branch of this PR (which I’ve already done) or change your base branch to dev-sign (though this isn't simple).

Why don’t we just use the main branch for this PR? We can decide when to merge it once the reviews are completed.

[Deafveloper]

@seokho-son Yes that is exactly what happened. I changed the branch after my commit. I’m still getting the hang of the Git/GitHub branch concepts, so I appreciate your patience.

I’m happy to learn and follow any steps you suggest.

Thanks again for your help!
