I’m having the exact same issue. Keen to hear what the solution is.  One day it was working, the next it isn’t.  

In the mobile app, go to the tab You > tap the gear wheel in the top right corner to open Settings > scroll down and tap Data Permissions > Health-Related Data > set to Always Allowed

It was already set to ‘access allowed’.  I’ve tried logging out and back, deleting app and reinstalling.  Even replaced battery in my HRM.  But still not saving the HR data at end of run.  When I click ‘finish’ at end of a run it comes up with a ‘something went wrong’ red banner at the top, but does save all of the other data from the run. 

Adding in that I am having the same issue and looks like some others also are based on the posts here. Seems to be a new bug introduced within the past week.

thanks for the additional information… I’ve asked the moderators to have a look and to pass the information to the engineering team - hopefully it gets fixed soon!

I have had exactly the same problem for some days!

I’ve been having this issue also, since the 414.0.0 update…

Using an iPhone 16, w/ ios18.5, everything within the app was working as expected. Did a ride the morning of June 5th, HR data was recorded, updated the app to 414.0.0 that evening, next day’s ride (June 6th) the HR data not saved. Did a bunch of troubleshooting, rode yesterday (June 8th), still no HR data being saved. While recording my rides, the HR is being shown, my HR monitor is connected, but no HR data being saved at the end of the session.Hope this gets resolved,it is one of the key reasons I use Strava.

Hello Everyone,
I can confirm this is a known issue by our team however a fix is already being worked on.
We expect this fix to be rolled out soon.
I’ll be sure to return to this thread once I receive word the fix is pushed out.

Thank you!

Hi adding on this, I also experience similar case where my heart rate data (avg HR, max HR) are not displayed after i finished my workout. Before I started my workout I’ve connected my Huawei Fit 3 watch with Strava via HR sensor and when I do my workout the HR data still displayed. However after I finished the session, the only data displayed is time. 
 

Previously it works fine but since 3 days ago the HR data is not displayed.

I have a MOOFIT heart rate monitor model HW401-23394.  Heart rate shows during activity but is not retained.  The Heart Rate Insights section is saying that no heart rate monitor was connected.  This did not happen when I first usefd the monitor.  The failure started on June 6, 2025.

I have the exact same issue since June 6 (on June 4 it was fine) with the iPhone app and my POLAR H10 heart rate sensor. Heart rate data showing while riding my bike but not available after finishing and saving the ride. Please fix this soon! Thank you! 

same issue here. iPhone 13 and some kind of standard chest based heart rate monitor.

Heart rate showing perfectly. Done with workout, heart rate info gone. Annoying.

Hope they roll out the fix ASAP.

ALL - TODAY’S UPDATE FIXED THIS ISSUE FOR ME.

I am running the Strava app on an iPhone 15 Pro running iOS 18.5.

Good luck!

Same issue here with a garmin chest strap.

I’ve been experiencing this issue since Friday 6th June. It affects my cycling and workouts. Currently using an iPhone 14 Pro on iOS18.3.2 paired with a garmin chest strap. I have tried using an old iPhone 8 and that is also experiencing the same problem.

Same here, problem started June 6th, Sigma strap.

Version 415.0.0 rolled out last nite, hope this is the fix we are looking for. Will find out later today.

Kudos Strava

Seems like it’s been fixed by the new version

Hello Everyone,

I’ve received word from our team this issue should be fixed.
If you haven’t done so already please make sure to update your app to the latest Strava app version.

Thank you all for your collaboration & patience in resolving this issue!

I installed the latest update (415.0.0), but still the same issue.

I’m pleased to say that the update solved the issue for me.  Thank you Strava app engineers
