Seems ok @nikolaglumac

[ManusMcCole]

On MacOS only there is an issue where the loading box flickers when a selected wallet import is loading. The box intermittently dissapears and reappears. Wallet import is succesfull it is just quite slow

[nikolaglumac]

@ManusMcCole I don't see this issue on my mac. I believe this is due to the fact you were testing on a macOS VM.
@DeeJayElly @daniloprates @tomothespian please test this on your Mac's and let us know the results.

@DmitriiGaico @IuliaDolishniak @gnpf please check if you can reproduce this on Linux/Windows and please make sure to use real machines and not VMs.

[nikolaglumac]

@DmitriiGaico I have added a fix for https://jira.iohk.io/browse/DDW-163 into this PR. Please test that as too 🙏

[DmitriiGaico]

@nikolaglumac Disappearing button is showed for MacOS vms only. At Linux/Windows button works as expected.

[nikolaglumac]

@gnpf @alan-mcnicholas can you confirm this bug on your macOS VM?

I would like to hear if any of the developers face the same issue on their real macs @tomothespian @DeeJayElly @yakovkaravelov @daniloprates 🙏

[darko-mijic]

I can't reproduce this on a real Mac with the installer from this PR.

[ManusMcCole]

Gabriela also experienced this issue on her Mac VM on Friday

[nikolaglumac]

OK. If this can only be produced on VMs then I am fine with ignoring this issue...

[darko-mijic]

Completely agree @nikolaglumac. Merge away.
