Cannot interact with an anchor program on mobile

[AlexScotte]

Summary

I'm trying to call methods from a contract coded with Anchor and deployed to the Solana testnet.
I am unable to call the different methods and sign transactions and no error message appears. I am sure that this does not come from what I call my contract or from my contract itself because everything works well with 2 other wallets.
When I try to sign a simple memo there is no problem and I can sign the transaction
(I'm using solana-mobile/mobile-wallet-adapter-protocol to connect the wallet, but i've checked with the team and we don't think it comes from their side)

Thanks for your help !
