I'm using IDE vers. 1.8.19, perhaps that's the issue here, but Paul Stoffregen's Time library will not update, it is stuck on 1.5.0.
It says it is installing, but the progress bar at the bottom of Library Manager does not fill, even though it says it is updating the list if installed libraries.
When "finished" it still says I have 1.5.0 installed.
I've just updated a load of other libraries with no issues.
Anyone know what is occurring (or not occurring, lol) ?
If you enable verbose output during compilation under file → preferences in the IDE and compile a program that uses the offending library, it will tell you where it found the libraries and which one it is using; I suspect that you have a library hidden somewhere that you have forgotten about. E.g. I have two servo libraries (don't ask why), one is the one that comes pre-installed with the IDE and the other one is in the libraries directory in the sketchbook directory.
Multiple libraries were found for "Servo.h"
Used: C:\Users\Wim\Documents\Arduino\libraries\Servo
Not used: C:\Users\Wim\AppData\Local\Arduino15\libraries\Servo
You can use this to find the libraries and manually delete them.
