I am using Todoist for a number of years and is becoming more and more unreliable with many unfixed bugs. Really so many bugs and the worst of all is that nobody fixes them even though they close the raised tickets! Although the customer support responds relatively in an ok timeframe, there is usually no successful resolution of the issues raised. More than 10 issues I raised are still unresolved and I have not received any meaningful update. Also, many features are half-baked such as the location reminder feature that can only be assigned to yourself although for other reminders you can assign them to other people. Literally, so many things are wrong, that is a waste of time to report them as they will never get fixed.
