Customify Pro compatible with WordPress 5.3?

Hi,

1 – Went to update Customify Pro to 0.1.1 and I get the message:
“Customify Pro
You have version 0.1.0 installed. Update to 0.1.1. View version 0.1.1 details.
Compatibility with WordPress 5.3:Unknown”

2 – When I click on details I get he following:

“Plugin not found.
Query Monitor
The message above was triggered by Core.
Call stack:
wp_die()
wp-admin/includes/plugin-install.php:527
install_plugin_information()
wp-includes/class-wp-hook.php:288
do_action(‘install_plugins_pre_plugin-information’)
wp-admin/plugin-install.php:70”

3 – I tried to update a localhost copy of my site and I get this message”
An error occurred while updating Customify Pro: Download failed. Unauthorized

4 – I then went to Appearance>Customify Options and saw this message:
“Customify Pro License
To receive updates, please enter your valid Customify Pro license key.
Your license key has reached its activation limit.”

5 – However – I only use the theme on one site – the site in question. (and a local copy of it – which should not matter as it’s a local duplicate for dev purposes)

6 – I wrote Customer Service on the Press Maximum site – and have not gotten a response (I sent that last week).

Hoping someone can shed some light.
Thanks!
