UTM parameters and “auto send push notifications” settings don’t seem to work

Hi guys,
First of all, thanks for the great job with this plugin. It’s been really usefull for my website.

I’m having trouble with the “Auto Send Push Notifications” settings. It seems that the options I choose and save on that sections of the settings don’t work.

I have choosen the option “Use Large Image” and saved several times, but somehow the notifications are always sent with the small logo image.

I have also choosen the option “Auto Push UTM Parameters” and filled source medium and campaign, but the notifications are always sent without the parameters.

Besides that, everything seems to be right, I’ve check several times. All the other settings when changed work fine, but the setting on “Auto Send Push Notifications” don’t seem to “stick”.

Thank you so much for the help.
Best regards,
Marcos
