Foot POD drop outs in gym with Fenix 5+

Hi there. I recently posted that I was experiencing signal drop outs with my Foot POD and HRM-tri while using my 935 https://forums.garmin.com/forum/into-sports/running/forerunner-935-aa/1430923-foot-pod-hrm-run-drop-outs-in-gym This is while running on the treadmill at my gym. I place my watch on the treadmill and rely on the Foot POD for pace and cadence data. I now have a Fenix 5+ and experienced the same issue yesterday, this time only with the foot POD and not the HRM-tri.

In the attached pic, for the first 12min the pace data drops out for just a second or two. Previously this was thought to be due to interference within the gym potentially coming from wifi.

Could I please get some help having a look at the file - any thoughts? ciq.forums.garmin.com/.../1451197.png
