@siddarthkay is it possible that this is missing the previous fix or that the docker cache wasn't refreshed? Because I see the first issue: |
|
@jrainville : its possible, let me purge docker cache in all CI hosts |
@siddarthkay I just tested. I restarted my PC for a clean state. First run was ok, but closing and then reopening, same problem |
|
Same problem, though while restarting my main release app, I found something interesting. If I run the app, login, then quit, on the next app start, the reader works. So maybe you change needs to be applied for before login too? |
|
Hmm interesting @jrainville : Thanks for testing! I'll mark this PR as draft and test with my linux PC tomorrow! |
|
sadly when i close reopen the app, the reader is invisible for the app
