As per the title, the repay button for MATICX vault just does nothing. I can't repay MAI to the vault.
Edit 1: I tried to partially repay MAI but the button doesn't work. Does it mean I have to pay back all of my debt at once?
Edit 2: I managed to payback by interacting with the smart contract. If you have problem like me then this is how I did it:
  1. Go to the smart contract that handle MaticX vault by entering the address on polygonscan.com: 0x4b7509ce029656341D0B59D387D9B5312E41615a
  2. Click on the "Contract" tab and click on "Write Contract" underneath
  3. Connect to your Web3 wallet
  4. Click on "payBackToken" function
  5. Enter your vault ID
  6. Enter the amount you want to repay without the comma and fill up the decimal space with 0. Ex: MAI token has 18 decimals so if you want to payback 10 MAI then you'd have to enter 10000000000000000000
  7. just leave _front at 0
  8. Write
