Switched from Apple Watch Series 6 to Forerunner 265s

So far I really dig it, especially the battery life. My Apple Watch lasted 36 hours max if I didn’t workout or use it much. The forerunner is a huge upgrade.

I’m hoping you guys can help me troubleshoot a couple of things though as finding answers online is giving me info that doesn’t work and is sometimes vague.

1) I have a HR-based marathon training plan from training peaks. How do I turn off the notification when my HR isn’t in the correct zone? The vibrations and pings when I’m running is getting annoying.

2) is there any way to set up an alarm from the connect app?

3) What exactly is ConnectIQ? I feel it’s important but so far I can’t find anything to actually use on it. Do you have any favorite apps for me to look at?

4) I can’t get the weather to show on my Home Screen on the watch. I have an iPhone, and I’ve already restarted the watch to no avail. Any one have solutions?

Thanks!
