Here is something that may be worth trying.
Have the Excel GetCell access and setting of Buttons2 in a different block, triggered by another button for test.
Or alternatively, put a small delay (wait 1 second) just before the airtable access.
What I am wondering is if the process of accessing the airtable is delayed because of all the other things the application has to do at start-up, basically getting some stand-in answer before the device had the time to query the table.
I think that an error with access to this table. What is in the “error” block? Check all fields for access to AirTable - APIKey, BaseID, TableName, ViewName.
First of all, it is better to check with the help of the GetAllRows block whether the data is returned from the table.
