GFCI trips after adding new circuit to it

gfci

Preface: I am a complete newbie when it comes to electrical circuits. I usually have electricians do all the work in our house.

An electrician installed a circuit in our backyard with 8 outlets on it. The circuit was controlled by one GFCI.

Everything worked fine, as expected.

A couple of years later, another electrician added another circuit with 2 outlets and an air conditioner compressor to the same GFCI.

Now the GFCI trips every few minutes.

Obviously adding the new circuit has something to do with the GFCI tripping every few minutes. But beyond that I don't know why this is happening and how it could be fixed. Any suggestions? Thank you!

If you have too many receptacles on a 15 amp circuit this would be the issue as an AC unit will draw some current
