Assuming you didn’t sent it to a Bech32 type segwit address that starting bc1, eg: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq

In the bitcoin wallet electrum, you will be choosing two types of segwit address, right? One is for P2SH nested segwit that starting in 3 and the other one is for native segwit that starting in bc1.
Nested segwit in a P2SH type addresses starts in 3 the usual bitcoin address that we have in coins.ph and assuming that you probably sent it in P2SH type of address or nested segwit because sending to a Bech32 type of address won’t work using coinsph.
