I would recommend trying a few things before contacting Apple Support:
1. Restart both your iPad and the Bluetooth speaker: Sometimes a simple restart can fix any software glitches that may be causing the issue.
2. Forget the Bluetooth connection on both devices and pair them again: Go to Settings > Bluetooth on your iPad and tap on the "i" next to the speaker's name. Then, tap on "Forget This Device." Then, pair the speaker again.
3. Update the firmware on your Bluetooth speaker: Check if there are any firmware updates available for your speaker and update it if there are.
4. Reset network settings on your iPad: Go to Settings > General > Reset > Reset Network Settings. This will reset all network settings on your iPad, including Bluetooth connections.
5. Check for software updates on your iPad: Go to Settings > General > Software Update and check if there are any updates available. Install them if there are.
6. Contact Apple Support: If none of the above solutions work, it's best to contact Apple Support for further assistance. They may be able to identify and fix the issue for you.
I hope one of these solutions helps fix the issue with your Bluetooth speaker and iPad. If not, contacting Apple Support would be the best course of action
