Hello Jalal,
Backend sequences should not last too long as this will cause wait Sign to be displayed during this time.
If you have too long processing times in the backend We suggest :
1) Split your backend sequences into subsequences lasting a fraction of the time
2) Have the Client call the sequences in // if possible (A subsequence does not depend on another) by placing call sequences as siblings under the onTap Event… In this cases all the sequences will run at the same time, rendering more quickly…
3) Or, Have the Client call the sequences one after the other by placing call sequences one under the other… In this case, the client will render some data at each sequence completion, having the user to see some progress in the UI.
Hope That Helps
