A potential reason for an interrupted iOS update could be a lack of available memory on your device. The update process requires some temporary storage to download and install the new version, so if there is not enough space, the update will remain in a paused state until more space is freed up. Another possibility is a problem with your Wi-Fi connection. If your network is unreliable, the download speed can slow down and cause the update to pause. Other factors that may contribute to a paused iOS update include: -Temporary unavailability or congestion of the server -Your device being stuck in recovery mode -Issues with Apple's servers.
