I've been trying for a week now to deposit some funds but these two problems keep occurring:-
1/ The walletconnect function doesn't work very often. I tried initially linking it to my Trust wallet, I used three different browsers, two different computers and my phone. I've deleted the Trust wallet app and reinstalled it. Nothing. I then discovered i could use walletconnect with my ledger nano, so I tried that. At about the third attempt it connected so I tried to deposit DAI which led to this issue:
2/ When I deposit DAI, I get a screen that says 'Approving DAI' and then it just hangs for a few minutes before reverting to the previous screen. I try again and again with the same results.

It doesn't always connect to my nano with walletconnect - I'd say it's about a 1 in 5 success rate - but even then I can't deposit funds.
What is happening, and what can I do to change it?
