Unable to unstake LP on a Mac using Mdex (HECO)

[hieronymus4826]

The wallet connect and interacts with the dapp, but fails on the last step.

The user has provided a step-by-step video here: https://youtu.be/4vH1PgA9pM4

Unfortunately, I can' replicate. The website is unreachable for me (in Bulgaria). I've tried VPN, mobile networks, UK hotspot and nothing connects.

For posterity, the dapp is at https://ht.mdex.com/#/swap

@hieronymus4826 I have managed to reproduce the error. The video from the user was very helpful. It looks like it's something the dapp has to fix. When I tap on the Confirm button to remove liquidity, this is what appears in the web browser console:

I have attached the textual version and took a screenshot. Maybe ask the user to ping the dapp's developer with these?

Thanks, Boon! I will update the user and forward him to the dapp support itself. Will update here, if we get any response there.
