Help: Bubble on the surface of my trapeze

I feel like I've read about a similar problem before, where the leather was detaching from the lining a bit and causing bubbles. Not sure if they found a way to fix it :sad:

Yup, that's what I recall being the conclusion in another thread.

Sorry this is happening, OP.
