My Avax API syncs aren´t complete at the moment. Swaps show only one part of the trade. NFT trades only show the NFT side of the trade and not the WAVAX change.
The wallets with C-Chain transactions only seem to be fine.
The wallets with C->X/P-Chain transactions give errors.
Is that the case for you too?
EDIT:
Here are some example addresses picket from snowtrace:
0x014c372fCEF84fe3e07F45C152A40D26aBbF473e → no exports, does sync correctly
0x8d6B9537C08eBa898e7e5037D5685FC2DB4ae83d → P-Chain export, leads to error
