Month widget doesn’t work

I have been using the app for a short período of time and the month vow widget is the principal feature for me, but I have experience several issues with it. 
when i insert the widget, everything seems to be working properly, after a few days the widget appears completely white, with no information at all. I have to delete the widget and insert it again to have it working for another couple of days. 
It’s disappointing and annoying have to always repeat this procedure in order to have this feature working. 
I’m almost giving up this app, even though I’ve already paid for the license. 
Do you have an estimated ETA to fix this issue??

Thank you. 
I’m waiting for you answer.
