I have a Redmi Note 5A with MIUI 11.0.3. With my previous phone, a Galaxy S5 neo, when I ignore reminders, there is still a notification which stays forever until I finish the task or delay the reminder. Even when I reboot the phone, they come back. Now, the notifications just disapear for no reason. I enabled persistant notifications and alert mode and ticktick has battery optimizations disabled. What can I do to keep the notifications ?
