fenix 5X Plus keeps asking about HRM-Pro+ data even if strap is disconnected

Hi all,

I have had the F5X+ for years with a HRM-Run and it has worked flawlessly until the strap started misbehaving. Replacing it with a HRM Pro Plus, everything is good when running.

When I swim (pool), without the strap, after an activity the watch keeps asking about the strap data even if I disconnected it before the activity. This results in having every time to wait some timeout of the search and confirming few times that I really don't want to include the strap data.

I searched around without success.

Any hint?

Thanks!
