While there are times where I introduce a bug or three which cause issues, it is most likely a case of too many user accounts logged into one browser. Please be sure you are only logged into one account when opening this (or any) Google add-on. It is a known Google issue: https://developers.google.com/apps-script/guides/projects#fix_issues_with_multiple_google_accounts
Great question! We have a Google group that is dedicated to issues. There are many people on there who have probably had the same problem you're having, and I am constantly checking it to see if I need to reach out directly. Here is the group: https://groups.google.com/g/doc-variables----support-and-requests
If you don't feel comfortable posting there, then email me at email@example.com . Be prepared to share a copy of the document you are having trouble with so I can debug it.
Hey, thank you! I really appreciate it... This is a solo-endeavor that require a lot of time to support. Domain subscriptions do not require you to register users directly. I have a report that is sent to me of all domain subscribers and the number of active users in the past 30 days. If your number goes over the limit, no one will lose functionality... I will just email you and ask you to upgrade.
Well, aren't you awesome for asking. Obviously, if you find this has saved you time and you use it regularly, I would greatly appreciate a subscription. But, it's not the reason why I do this... I love this app and I am very proud of it. If you like it, then I would greatly appreciate a review on the Google Marketplace. It helps more people become aware of it and use it... which makes me happy!
