SafeProxy contract is not deployed on the current network, but only on a mobile browser

[miohtama]

Bug description

We try to sign a multisignature transaction for Gnosis Safe. We are getting error "SafeProxy contract is not deployed on the current network" but only on particular wallets/browsers. Thus, not all signatories can sign the transaction, unless they change wallet/browser.

We are not exactly what caused this, but we suspect it is related to the user of a mobile browser (Safari/iOS). We had to sign the transaction any way, so we cannot repeat the issue for this transaction anymore.

Environment

The transaction is on Arbitrum One.

Environment that works:

• macOS, Chrome, Rabby wallet

Environment that doesn't work:

• Trust Wallet (iOS)
• SafePal (iOS)

Steps to reproduce

1. Open mobile broser
2. Go to Transaction list
3. Click transaction
4. Click sign

Expected result

Everyone can sign the transaction normally.

Obtained result

Some users get "SafeProxy contract is not deployed on the current network" error. Other users can sign just fine.
