This app keeps asking to upgrade because there are more than 100 collections, even if you disable enough collections to get the number of collections you need it to manage to less than 100. Doesn't send you notification either that it has stopped working until you upgrade unless you go into the app itself. An email would have been appreciated.
Thank you so much for the feedback provided and we are sorry if that was not clear that the app defines the required plan based on the total number of collections and products in a store. As for the email, it is a wonderful suggestion and we will certainly introduce before the end of the month.
