Got fired for clocking out on my app when I left - Food Runner ByteDance Employee Review

I got fired because I work for an app I clock in and out of the app. I clocked in with the app. So I clock out with the app. Service for our phones didn't work. I didn't get the password for the Internet like the others did. I was actually focused on the job. But, I asked her if I could stay for the rest of the shift which was like 10 /15 left. She said no but I was schedule to 4:30 But it was a whatever situation. Again no service. I wrote the time that I actually clocked out on the paper that provided us. But I still also clocked out of the app that I clock in and out to and assuming they will change it because they had the time. They fired me instead. And if not because of that it's because I am pregnant and they knew that. So, for my advice.... I feel like Instead assuming the worse in people thinking that they were trying to get over or something maybe you should ask or understand why I clocked out on the app. It has a location where it shows where I am. Again there is no service in the building at all!!!! I never got the Wi-Fi password. Other than everyone else I was actually focus on the job and not on my phone. And if that wasn't the cause just because someone is pregnant doesn't mean they can't do the job. I am only 9 weeks But I feel that wasn't the case. I really liked the job and felt like I was mistreated by being fired. We have to clock in and out of the app and I let them know and I also ask them if I will be able to get paid for the last 10/15ims of the shift that they said I would be working. Which I am not wrong for asking questions. I feel completely insulted and disrespect my this company.
