Recently, the changes could have been made and introduced by AppSheet to construct the URL to reach out to the sample app you made.
Bug Bug fix for rebranding Sample Apps to Templates. The route
samples/?appGuid was not working properly for users inside the rollout. Now
templates?appGuid is supported.
Still it was not clear even after we reviewing the recent announcement by the team.
I check and tested to learn how to manually construct URL for sample app, and found a working formula. Still not sure if it is well founded, so appreciate for AppSheet team interation to this topics.
Firstly, this is one of the recently working sample app url. This is taken from one of AppSheet sample (recently renamed to Template)
Then this could be formulated to :
Just replace APP_ID with your own app unique App_ID
For the part of ANYTEXT, you can change it over to any arbitrary text, but you can not omit this part.
