There is an easy to fix bug; although since there would be zero help from support (they are fast with watch replacement but zero help with bug fixes), I'll leave bug report here.
On 945 (like most of other Garmin watches) we're limited for 2 CIQ datafields maximum at any standard activities. If I have two CIQ configured and want to switch one of them third CIQ, I can't easily do this as 945 is saying that "you have maximum 2 CIQ datafileds, please remove one of them....". Which sounds stupid, as I'm replacing one CIQ into another CIQ. So, I have to switch CIQ datafiled with any standard first (let's say with a timer field), and then switch timer field with new CIQ datafield.
In previous releases (2. and 3. something) we could easily swap CIQ datafileds without need to change one of them to standard datafield.
It is so annoying, and it so easily to fix. Can please someone from Garmin take a look at that issue please?
