Explain the problem as you see it
It's more an opportunity then a problem
Now Tana is on mobile, a set of not surfaced use cases that will impact positive on the user arrived
Let's start with a sample to get an understanding of what I have in mind.
Imagine I have a shopping list, and a task to update my contract at the mobile provider. I am arriving supermarket "X", where is also an office of my mobile provider.

So now we get next to the date and time reminders, also the option to location sensitive reminders, if the user gives permission of course.
Why is this a problem for you?
I can put a reminder that on Friday 08/09, I have to purchase certain things, and most probably I will go to the supermarket.
Will I remember to renew my contract, not so sure about it, because it's not really to the time / date related, but more to my proximity of their office, to be reminded.

Talk about information flowing to where/when it's relevant!
Wow great idea!
针对这个问题，提出一个解决方案供参考
在 omnifocus 中，可以设置一个定位点，在action设置中添加这个定位点并明确到达这个定位点的多远距离来提醒，这样就不会错过提醒，可以了解相关的功能
In response to this problem, a solution is proposed for reference
In omnifocus, you can set an anchor point, add this anchor point in the action settings and clearly indicate the distance to reach this anchor point to remind you, so that you will not miss the reminder and you can learn about related functions.
