Unable to connect wallet to Etherscan "revoke feature" to canx ETH Unlimited Contracts

User reported bug via support:
Cannot connect to wallet to Etherscan, objective is to revoke Uniswap approval (Unlimited ERC20 allowances!)

Steps to reproduce the behaviour:

1. Tap Browser
2. Insert Etherscan Contract url: https://etherscan.io/tokenapprovalchecker?search=0x39063c32ebef4b026609ef841b8203e52de68630
4. Cannot connect wallet ---> cannot show

My screenshot where I've replicated the UX:

Interim workaround:

Quick fix for this user to stay inside Alphawallet -
1. ask user to navigate Browser
2. use this Url Eth Allowance / Revocation tool: https://james-sangalli.github.io/eth-allowance/
3. Wallet should automatically connect (To be confirmed, waiting for user to respond)
4. User to click "revoke all allowances"


Resolution:
- pending user confirmation that workaround point 3 works
- pending user confirmation iOS / Android (version number)

Background:

Etherscan has a new Token Approvals feature released (2 months). Unproven projects with novel yield farming have reaped more and more token allowances - to the point where they just start stealing user tokens. Reading: https://kalis.me/unlimited-erc20-allowances/
