I was whatsapping my friend when the power went out.

She's WhatsApping her colleagues about the meeting while commuting.

I'm Whatsapping my colleagues about the schedule so we can finalize the plans.

She Whatsapped me the photos after the party.

She WhatsApped the meeting notes to the team after the call, so everyone could review them.

She whatsapped the group to remind them about the meeting, and everyone confirmed.
