Before the test
Keep .app and .io quotes separate until the same operator and account terms are documented.
One test result
Use the same screen and programme for one short control run. Record the app version, network path and which feature worked. Keep all account fields private.
Decision record
Write down any terms the provider supplied and which two features are essential. Keep results for the guide, playback and account access in separate columns.
Find the recovery path before you change players
Try the account on the original screen before signing in on a replacement. If the new app has a different input form, take the public field names to support without sharing values.
