Verified via blockcypher and other block explorers that there is a balance at 33zdGuXTtuX7eiCiFb2g55KAyShKFzPxJv

See https://live.blockcypher.com/btc/address/33zdGuXTtuX7eiCiFb2g55KAyShKFzPxJv/

Zapper shows no balance, but other addresses seem to work.

Is it because it's a SegWit

P2SH account?

Thank you
