FYI
Some of the FlexUG4 packaging has a lube packet attached to the outer packaging.
This may cause interference when trying to read or write.
if you create some seperation between the Lube sachet and the FlexUG4 ie. Slip a finger inbetween or if you really “have to” then seperate the packages carefully.
But be warned, The glue is quite strong.
If you dont need to mess with it, then just wait until you are ready to install
