Why are all images file in Firestore storage render every time when switch from tab to tab

Question

I'm a basic learner of using Firestore which is connected to the mobile app (react native). The app is rendering the image url every time (type data as number and string are okay) when I switched from tab to another tab (react-navigation/material-top-tabs). But when I used another public image URL then store in Firestore, it's working fine...no re-render the image url.

So, may I know the root cause that is it because of Firestore Storage or else...?

Thank you so much
