WhatsApp online/offline issue

[Android Central Question]

Hello to all!
I have a big question and the right replies will help me a lot (more thant you should thinks...)
I live in Italy and Ive a 5g Zte 72A smartphone.
This morning I was on a train and my signal wasn't perfect and I think It's normale during a train trip...
What's happened? That my gf wrote a message, I've replied normale but she goes crazy because, she says, I've modified my status to offline in privacy settings (to be anonymous I think...)
I'm an old guy and for me WhatsApp It's like a SMS service upgrade with photos and videos and files uploader and I think It's Always online because you write me and I receive your message. I never changed this setting because first before today I didnt know that and second I didnt modify NOTHING.
How It's possibile that she saw me offline but I was online because Ive never changed my settings? Glitches, bugs, WhatsApp down of two days ago??
Thanks a lot for all replies.

Signore, un uomo non è obbligato a rispondere a tali domande, né a pensarci. La tua ragazza deve pensare come vuole.

Some temporary technical error probably, yes.

I get that all the time if the sender has poor internet connection last seen timestamp will be earlier than the last message that was sent. Other times it just won't show anything about last seen until it syncs again.
