debugging using system log

[md_sgf]

Macrodroid is freezing/crashing several times daily now

I have tried these things:
• Clearing all backups except one
• Clearing cache
• Restarting phone

So I am wondering if I need to investigate the system log. As I see many errors/warnings (such as ~"... enormous ... memory usage ...").
But I want to know exactly what I need to do. I don't want to mess around (trial'n'error) with things I don't understand, as that would be a serious misuse of my resources (time, energy, patience, ...)

To kick things off, what I have done is this: (basically, de-selected everything)
• De-selected all macros
• De-selected all variables
• De-selected Triggers, Actions, Constraints
• Set to Errors
• Cleared log

So I guess I will go through EVERY error/etc that exists, one-by-one, and resolve any issue with it (if there is one)

 

[md_sgf]

The first entry after I did above, is: "Constraint check failed. The setting (<my phone name>) does not exist on this device: <my phone name>
How do I deal with this error?

I wonder if I should try what MacroDroidDev says in here? ---> MD crashes when trying to view my system log

Please use report a bug in the troubleshooting section as this will send me an anonymous crash log id that I can use to try and find your device in my crash logs (which is the easiest way to understand exactly how it's crashing)
