If a friend ignores your messages (you can see online that they are not busy), would you just leave it be?

My friend has been doing this quite a lot lately. Occasionally she will reply but often she wont. Fair enough if they dont know what to say, but it kind of hurts. I also gave them an online membership for something as a gift so we can play a game together (was a way to spend time together during lockdown)...asked them to let me know when they are playing so we can play...even just once together...they haven't.

These things on their own arent a big deal, but it's just all the times added together, I've felt a bit ignored. I've just kind of tried to leave it, if they dont want to chat that's up to them. 😅 Chances are they also forgot.
