Sent some BTE and it now has 5 of 6 confirmations so looks like send is working OK as long as mining is ongoing.
Received. Thank you.
Quite annoying at the time as the difficulty used to skyrocket and if one didn't have lots of hash power one had to wait for the difficulty to drop again to do any mining.
This is a common problem. Difficulty gets blasted into orbit, then abandoned. The blockchain then gets stuck.
Why not start mining with me while the diff is currently really low? It's only 5436.852907928366 now, which is about 38.92GH/s for a 10 minute block target.
Point your miner at
stratum+tcp://bytecoin.pool.chainspy.com:3001
username = <your bytecoin address>
password = x
Try
https://www.miningrigrentals.com/ if you don't have your own equipment.
You need to rent a SHA256 rig. Really cheap. In fact, you'll struggle to find a rig with such a low hashrate.
Don't blast 100TH/s at it.

Considering setting up mining on another machine I have. Need to set up v 27 and check out some antique miners I have for suitability. Will get back to you on this.
A few questions,
1) V 27 did not create a bytecoin.conf file in AppData\Roaming\Bytecoin. Is this normal?
2) V 27 entered a bunch of bech 32, etc addresses in the Receiving Addresses window in addition to the Base 58 addresses that were added when the old wallet was recovered and migrated. Where did these come from? Can I delete these?
3) Can't see the sending address that was used when I made the send. The address showing in the Sending Addresses window is the same as the address I sent the coin to.
4) How do I open port 6333 to receive incoming connections?
TIA.
