I have Mycelium V18.104.22.168 installed on my phone. I have sent BTC from another wallet to the public address shown on my Mycelium apps front page (the "Balance" tab).
I sent these funds using Electrum. The transaction now shows on the Blockchain; I have checked using Bitref.com. On Bitref I have checked the same public key as shown on my Mycelium app. Specifically the public key on the "Balance" tab that I can copy (and a QR code of which is shown).
It has now been more than one hour since the transaction appeared on the blockchain but the funds still do not show when I refresh Mycelium.
The transaction now has 4 confirmations, as checked using https://www.blockchain.com/ -> Explorer. Still it is not showing in Mycelium; which I thought required only two confirmations.
What are the possible causes of this?
