Hello,
it’s possible to link my glide application with a new gmail account
It depends on what you mean by link the account.
Assuming what you mean is move the account. If you have a Glide app and you want to move it to a different gmail account. You can set it up as a template for all to copy. Copy it into that account, then turn off the template flag in the old one.
how to manage it with an PRO account ?
Send an email to support@heyglide.com and explain what you want to do. Make sure to include both app urls, like https://xzy.glideapp.io (Pro) & https://abc.glideapp.io as well as the emails used to login to each Glide account, if they are different.
