Hi,
Been using the pro version for a few years now and I changed to a OnePlus 6 phone yesterday. I migrated my setting from my previous phone ( Asus Zenfone 3) using the back up option. While setting up the app on OnePlus 6, I ensured that the Aqua Mail as well as Pro unlocker apps were not being optimized. The setting is for mail to be pushed every 15 minutes, but after about half an hour, the app stops pushing mail. I do get a system alert which says that the app is "heavily draining the battery" but the apps still show as not being optimized under the battery settings. So what could be the reason for the app to stop polling? The OS is Oxygen OS 5.1.5 with Android version 8.1
Any help to solve this would be greatly appreciated. Thank you.
