Recently I got hired as a software developer for one company in Western Europe. I passed the technical test and during my first week started working on my first project with only few hours of training in the technology stack they are using. I have one and a half years of experience with programming, but this the first time I work with this tech stack especially.
Even though it is only the second week now, I'm satisfied with my first commits. However, towards the end of the week I noticed that one of the features I was implementing is not really compatible with one of the browsers the client was using. I suggested a fallback option which got accepted and continued with the progress.
However, when I got home and checked the feature on my home computer, it worked perfectly fine and the fallback option was probably not needed in the first place. I suspect that what caused the issue in the first place was the laptop that I was given which was probably not configured properly.
My question is, how should I inform my colleagues during our next standup that the issue was actually my laptop and not the feature itself? I already spent a whole day implementing the fallback option and I'm afraid that this will look unprofessional since I could've done a better job researching the issue.
