I managed to sort my issue out by installing metamask and recovering the opera wallet through metamask.
I discovered my issue was not having Eth for transaction fee.
If the lacking eth isn't your issue maybe trying metamask will give you an indicator of thr issue

@lemonadeserg this is on s21 ultra android 11 and the latest opera mobile

I'm trying to send my crypto token but it's giving me an error saying network fee with red exclamation mark. This issue is also present in thr desktop version. The tokens are badger dao which are part of ERC-20. This needs to be fixed soon as its starting to cost me.
