There is a known issue with the ledger app sending pivx, a work around was created by one of the devs @random.zebra and can be found here. The other option is to rebroadcast the transaction which I can post here also, otherwise Id assume ledger will resolve the issue. From what I can see receiving on ledger works fine.
https://github.com/PIVX-Project/PET4Lif you have to manually broadcast the TX here are the steps:
1) Open Ledger Wallet App. Settings --> Tools --> "Stored Logs" Export (under "Diagnostic")
2) Save the file as a .zip file
3) Extract the two files contained in the zip
4) Open the file marked as 'private'
5) Search for a line starting with `Transaction,Raw TX:` and copy the hexstring that comes after that
6) Inside the core pivx wallet console do `decoderawtransaction "hexstring"` replacing "hextring" with the one you copied earlier. Verify that everything checks out.
7) Do `sendrawtransaction "hexstring"` to broadcast that tx to the network.
Just another example how great the pivx team is being able to help out pivians while ledger is having issues.
