After my previous post, have received all confirmations. Everything has been activated & the system is working.
Have found a couple of glitches, but generally it works well.
Probably the main issue is more to do with Samsung than Paypal. On my wife's Samsung, if you close the app to use the ph or another app, it automatically logs you out. So you have to log back in to use it. When this happens, it loses the connection with the card reader.
For some reason the app doesn't "remember" the card reader & won't re-connect. The card reader is still listed in the Bluetooth connections on the ph tho.
To reconnect the card reader, we have to delete the "old conection" from the bluetooth list, re-pair the card reader & then connect it to the app.
All of the above is ONLY using a Samsung Ph. My iPhone has no problems & everything works well & automatically reconnects as required...
