Can't seem to edit periods in app (android)

[blueisis02]

On my android app, I cannot seem to edit the length of my periods. I know that I can click the pencil and drag the days. However, due to the size of the screen and how the days are oriented, I can't properly edit my cycles. I can't manually enter in the physical days either.

For example, 

123456

7891011

My phone screen ends where the 6 is and begins again where the 7 starts. Therefore, I am not able to drag the circle to edit my cycles. 

Is there any way this can be corrected? Can I update this on-line?

Welcome on board @blueisis02, it's nice to see you around here! In settings, turn the predictions off. It will let you choose the dates. Once done, turn it back on and let me know if this time you can select your dates.

If a period doesn’t meet the following requirements, you may receive an error and be unable to log the period: 

• You can only add or edit current or past periods and details.
• A period must be at least 1 day.
• You can log a period of up to 60 days (on Windows 10 devices, the maximum is 10 days). If your period is longer, consider logging flow intensity details.
• A cycle must be at least 11 days, and there must be a gap of at least 1 day between logged periods. If you experience a gap in bleeding during your period, it’s still 1 period.

Note that If you attempt to log a period in the future or a period with less than a one-day gap between periods, the pencil icon is unavailable. If you don’t see the pencil icon, make sure the period you’re attempting to log or edit meets all of the requirements.

In regards to do this online. At this time, female health tracking is available in the Fitbit app for iOS, Android, and Windows 10.

Let me know how it goes!
