Start by reproducing the reported remove-liquidity URL on Polygon and inspect the source corresponding to the minified stack trace. Trace how the burnV3 state and chain ID are handled; done means the flow no longer crashes with “Unsupported chain ID” for this case and the relevant regression is covered.
