On my iPhone 6S the ToodleDo app is configured to import any new iOS Reminders as Tasks (Reminders Syncing turned on, with Delete after Import selected). However, when I create a reminder (using Siri) and then open the ToodleDo app, the app crashes about 90% of the time. The Reminder is successfully imported, but if I create 2 or more reminders before opening ToodleDo, only one is imported and the others are lost. This has happened for 5 years. Let me know if you want a crash log and I will see if I can capture one.
