Hello @everydaywiners,
After digging deep into the issue you are facing, I was able to identify it that the subscriber module issue still exists for some non-migrated users and have reported it to our developers and they have already started working on it and this issue will most likely be fixed in the next update.
However, the solution that I have provided above can be used only if you wanted to migrate to the changes but if you don’t want to use any of the starter templates and continue to use the page that you have now then I will advise you to wait for a little time till we release a new update.
Thanks for understanding and have a great day!
