When copied into the desktop browser, a series of images of lightning loop. When loaded in the webviewer, the same URL does not load properly and fails to loop. It seemed to start several months ago with the nb187 rollout, no issues with nb186. No similar problem with the URL in Thunkable.
Great idea, thanks for recommending. However, I tried the test server for nb188 and used the companion version 2.61tu as recommended, but the website still has the same error. Tried both standard and legacy mode with the companion. The issue occurs both when testing with the companion and in a packaged app.
