Good evening SimoneĀ and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the struggles you have experienced while attempting to update.
I would love to help you with this topic.
You are right, when you are not seeing the update notice, deactivating the plugin usually works (as long as your license is still valid).
Worst case scenario, it is sometimes necessary to completely delete the plugin and reinstall it from scratch (which causes no loss of data by the way).
Is there anything else I can help you with ?
Best regards,
Geoff B.
