                   <Text style={styles.messageText}>{item.text}</Text>
               </View>
           );
       }

@zhangwen9229 Did you solve this issue?
Same here

[zhangwen9229]

@zhangwen9229 Did you solve this issue?

No, this question, I gave up. I think my rn version is lower.

[dolphinflow86]

@zhangwen9229 It also happens in 0.63.4, could you open this issue again?
By the way, are you still using RN or changed to another(native, flutter or something else)?
Because I cannot find the proper solution for this..

I still use RN. Pull to load data, I think you can use loading, and add data directly.

I have same problem..

i had this issue when my renderItem took a long time to render for the first time. i changed it to a much simpler component and load in more stuff after its rendered for the first time and now i do not get this issue anymore.

nevertheless, should be adressed in this library to not request more while the previously requested component still isn't mounted.
