A4 mk2 sysex receive not working (need help)

So I have read a few threads, but so far haven’t found the answer.

I am trying to get some sound packs onto my A4 using the transfer app. My A4 is setup to send/receive MIDI via USB, set to receive Sysex dump to one of the empty +Drive banks.

It says WAITING DATA…

now I send the sysex file via the transfer app. Transfer says 100% / Sent.

The A4 still says WAITING DATA…

no files or sounds have been transferred.
Any thoughts?

Nevermind…after trying it a few times with the same settings and dis/reconnecting the USB cord it finally worked.
