install.sh saw - great work + thanks 
phoenixd vs andriod phoenix SEED are not interoperable - listen citadel few months ago or verify in doc
do NOT do it.
in worst scenario if their electrum or LN server are unreachable - using SEED (i think BIP39) it should restored on some generic electrum wallet + own electrum server +btcnode ?
does albyhub native node also similar last resort escape plan so can push funds to mainnet using electrum?
fees doesnot matter here.
when u see if throw some light. 

 just finsihed read albydoc - so nice 
Node section, click on "Advanced," select "Redeem Onchain Funds," and enter the Bitcoin address where you want to send your funds. 
So AlbyHUB n Phoenixd BOTH can move FUNDS to maninet
***only risk what if hardcoded ELECTRUM servers or node to broadcast are down/unreachable***
or SEED must able to be restored in compatible generic electrum wallet. i hoping so.
 

 Thanks for the digging but I don't have any funds to redeem on-chain, just 14 SATs remaining in the channel created initially.

It's more about the why to the same seed is providing  2 different node ID/pubkey.
