How big is the difference, like 0.01mBTC on your wallet and 0.00001BTC on blockchain.info?
If that's the case, double check the unit used by your mycelium android (ex.
BTC /
mBTC /
uBTC).
Those are Bitcoins (
1unit), MilliBitcoins (.
001unit) and microBitcoins (0.
000001unit) respectively.
It could also be a syncing issues if you've made an "
external" transaction before the last time it got synced like Bitcoin_Arena said above.
Some block explorers(including blockchain.com) do not support segwit, so if you have any BTC in bc1 addresses they will not show up
It's highly unlikely because of the bech32 SegWit compatibility, even though it isn't supported by that site, the "
bc1 address'" transactions were still included to each address' balance; you can't just click on it.
