Site keeps saying it needs license….and we added our unlimited license code

Hi!
We over the years have purchased this theme many times through MOJO. This summer, after reviewing the sunset noticed we saw that we needed to purchase something to enable ongoing support, etc.

We purchased an unlimited sites download through Lemon Squeezy.

We have entered that license into all of our sites on Highend and Theme shows green and that the license for unlimited is active in the Highend section.

– However we keep getting a message in WordPress that we need to enter a valid license.
– When click on the link it goes to section to enter license and it shows the unlimited license is valid on the site.
– Error message then goes away
– Next time we log into admin the error message is there again

Can you assist with why we keep getting this error in the admin saying we need to enter a valid license when it shows license is valid?

Thank you!
