Used too much joint compound

Hello again,
I am currently applying joint compound over new drywall. I guess I applied too much and all the corner joints have cracked I used fiberglass mesh tape underneath all the joints. My question is, should I try to sand it out, or just put more joint compound into the cracks. What is the best way to fix it( other than using less next time)

Thanks in advance

My 2: Remove the mesh tape and use paper instead. Not intuitive but it's actually stronger than the mesh stuff.

The next coat will fill the cracks but yeah, the paper is stronger and is easier to finish.

I also prefer paper tape

More j/c should fill the cracks but will that make the finished joint too high?

I went back to paper tape too but I wet it first. The putty knife slides over it so much easier.

Standard joint compound will crack when used with fiberglass tape and is likely what you used. With mesh tape you have better results if you bed it with a setting compound like durabond. Paper tape is less likely to ever crack no matter what kind of joint compound you use.
