Hmm...strange. I have my network synched up to date but it still shows in the MultiBit it's a Pending transaction. Maybe a reset could work?
Im almost certain MultiBit Classic because I hadn't touched it in a couple of years, so I'd guess Classic but not 100% positive.
Please excuse my newb-ness lol..
A reset should work, that's what I've done anyway.
I would recommend for you to export your keys (classic) and import your seed(HD wallet)/keys into Electrum. I'm certain that some of the Electrum servers won't have your transactions.
