A problem has been identified where some users experience significant delays when loading or displaying content while using mobile data.

This behavior does not occur when connected to Wi-Fi, where the application works correctly. The issue has been observed in the same physical location and across different mobile carriers, while other applications do not exhibit the same problem under similar conditions.

No exceptions appear in the error logs, which suggests that the issue may be related to network latency or intermittent connectivity, not reaching the threshold to trigger a timeout within the application.

That´s my code.
