For obvious reasons I'm going to be a little cagey with specifics but I really feel like I need a second opinion, especially from those with practical experience in running and/or participating in RPGs.

I feel like our current campaign sessions (my first TTRPG campaign ever, D&D 5E) involve a lot of wasted time and therefore little of interest occurring. This doesn't happen in every session, but our last few have felt especially bad.

Example, modified for privacy.

The party is hiding in a building. A giant (not sure what type) is outside wrecking things, and we need to figure out what to do. "Charlie", playing a rogue, suggests sneaking out to observe the giant. This leads "Bob" the fighter to say he wants to fight the giant head on. "Adam" the sorcerer says he can cast invisibility on two people, causing Bob to change his plan to one of escorting Charlie on the recon mission. This leads to at least twenty minutes of back and forth which doesn't feel meaningful or engaging. It feels like we've overcomplicated something simple. If I don't have a strong opinion I just okay the first plan that seems to make sense.

What eventually ends up happening is that all four of us exit the building. The giant either isn't aware or considers us beneath notice, the DM was intentionally vague on that, and we just skip town to escape what seems like an impossible fight. Charlie and I are of the opinion that we were wasting time, but both of us are new players. This is literally our first campaign. Adam and Bob seem a lot more experienced in D&D as a whole, including previous editions. Adam especially likes to come up with creative schemes that are sometimes fun and effective, but I feel sometimes things just get convoluted with him. Adam also tends to talk the most, and is usually the first to answer when the DM asks "what do you want to do?". As a counterpoint, the rest of us have a tendency to sit around with question marks floating above our heads. So Adam does get things moving, but it's a coinflip as to whether or not he'll start a ten minute ramble of trying to cover every single possibility, which can get quite outlandish and tedious.

I also have a tendency to get bored during the mandatory recon sessions that occur every time we find a new location that may or may not have enemies and dangers in it. I know why recon is important, but the way it plays out is just dull. Recon player moves, DM reveals and/or tells him what's there. The two of them just have their own little back and forth while I sit quietly and question my choice of hobbies.

It's not all bad. Sometimes we have interesting encounters (both combat and non-combat), go to interesting places, and meet interesting people. But when the dull feeling sinks in, where we're sitting around spending half an hour on a course of action, or one of Adam's schemes that go nowhere, it really kills my enthusiasm. We meet once a week, and spend about four hours playing.

To make things worse, we are playing online. I think that makes our communication a little stilted, with a lot of awkward pauses, though that might not be the biggest factor.

I really just don't know. When I review our session notes and think about how little we actually achieve, it feels off. But yeah, this is my first campaign and I don't know if my feelings indicate that something is actually wrong. Maybe it gets better as I get more familiar with the game. Maybe my expectations are off. Maybe my approach is wrong.
