Mobile.takeScreenshotAsCheckpoint(‘008’)

Hi em, could you take a look at this topic? Thanks

Elly_Tran · October 2, 2023, 3:44am

Hi,

I would like to clarify more on the issue that the keyword Mobile.takeScreenshotAsCheckpoint cannot capture full screenshot, is this correct? If yes, the bug has been addressed and we plan to fix it in v9.1.0.

asuncion.galan · October 2, 2023, 7:14am

That is, I can’t capture any screenshot, neither full nor partial.

Elly_Tran · October 2, 2023, 9:40am

Yeah, hope that v9.1.0 can fix this problem. Thank you!
