Thinh Dinh, You yourself (previously) responded to this message and I also created a bug report…
As mentioned in the text, this is a Glide table.
The setup is as follows: Several Glide tables are running in combination with a number of Google Sheets. The relevant Glide table (Products) is quite large by the way.
The Glide table where the data disappears is called A for the sake of convenience.
Via Google sheet there are different relationships with different Glide tables. 1 of those relationships is with Glide table B. From Google table A, various “lookups” are then done to other tables, including Glide table B.
Everything runs like a charm, days in a row. And suddenly (now for the second time) data (rows) has disappeared (about 40% the last time).
Regards and thank you for your response,
Ronald
