One possible solution to this issue is to check the settings on both your iPhone and HomePods to ensure they are configured correctly for playback control. Start by verifying that both your iPhone and HomePods are running the latest software updates, as this can often resolve compatibility issues.
Next, make sure that your iPhone and HomePods are connected to the same Wi-Fi network. Seamless playback control between your devices relies on a stable network connection.
Additionally, check the settings in the Podcasts app on your iPhone to see if there are any settings related to playback on HomePods or external speakers. You may need to adjust these settings to ensure that playback control remains with your iPhone even when using external speakers.
If the issue persists after checking these settings, you may want to try restarting both your iPhone and HomePods. Sometimes, a simple restart can resolve minor software glitches that may be causing the problem.
If none of these solutions work, reaching out to Official Apple Support for further assistance may be necessary. They can provide personalized support and troubleshoot the issue in more detail.
