intermittent audio cut-off with 2 troupers paired

i have 2 alto troupers, each works just fine when i connect my Bluetooth device to them on their own but when i pair the speakers together every 20 seconds or so the audio will cut out for a second or two.

This happens regardless of which speaker is the slave speaker.

is anybody else experiencing this / knows that cause of the issue?

it is extremely aggravating and is restricting the usefulness of the systems, thanks.
