Rate limit exceeded - installing themes - how to install more themes

I get error: : “rate limit exceeded” trying to add a theme.
I have two themes.

What can I do to add more themes?

Themes I have:

Error message - rate limit exceeded

I tried again the next day. I was able to add more themes. I’m concluding that there is some daily limit on installing Themes. I didn’t experience any limit installing Plugins.

I ran into the same error message when installing themes. Tried switching from the company wifi to tethering to my cell phone, and then it worked. Seems the public IP of the company network is being rate limited.
