How to train the iphone email app to suggest the right folder to move emails there from same sender/inbox
i use this feature to move emails from the same sender to a specific folder. For example i get notified from my credit card whenever there is a charge so in 2017 i moved those email to a folder named "expenses-2017" and in 2018 i moved them to a folder named "expenses-2018" and this year of course moving them to "expenses-2019". on an iphone 8, in 2017 it took almost from Jan to Oct to train the system to suggest the proper folder when you hit the folder/move icon. In 2018 it took until almost December 2018. And in 2019 for a few weeks in January it learned to suggest "expenses-2019" but then it went back to "expenses-2018". I get these emails 8-9 times a week so it shoud be reasonably trained by now. How do you reset or retrain this? the online search yield minimal information. Currently iphone 8, iOS 12.1.4...
