All Actions have limits for certain timeframes, ranging from 1x/year to multiple times per day. We believe that good habits are learned over time so we incorporate these limits in an effort to help set a good learning/practicing pace for the user. They also are intended to help people branch out and explore other Actions vs. logging the same action over and over throughout the day.
There are also limits within Challenges to help balance typical usage and healthy competition. If you're hitting these limits, wait a bit and try again, remembering to try and log as you complete actions throughout your day.
A couple tips for when you are doing a lot of great things every day: Log Actions as you do them so you aren’t trying to add many activities at once by summarizing an entire day. Also, utilize the quantities on Actions that you’ve completed multiple times. For example, instead of individually Logging Water Bottle 5 times, you can edit the quantity and select how many times you’ve refilled it.
