Description

Hello!
It seems that app does not update remote profiles when SFA is active.
Sometimes updates occur in time, sometimes with a delay of several hours, sometimes the profile may not be updated for several days.
I tried to describe a reliable way to reproduce the problem, but I'm not sure that it will work 100%.

Reproduction

1. Create some minimal config, empty json object is enough: {}
2. Put the created config in the https accessible directory.
3. Clear SFA app data.
4. Create remote profile in the SFA, enter url that points to the previously created config.
5. Enable autoupdate and set update interval to 15 minutes.
6. Start the SFA.
7. Wait 30-40 minutes and check profile last update time.

Expected behavior

Update time should be not more than 15 minutes in the passed.

Actual behavior

Update time is equal to profile creation time.
Checking the http server logs also showed that SFA requested config only once, during profile creation.

• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I confirm that I have provided the server and client configuration files and process that can be reproduced locally, instead of a complicated client configuration file that has been stripped of sensitive data.
• I confirm that I have provided the simplest configuration that can be used to reproduce the error I reported, instead of depending on remote servers, TUN, graphical interface clients, or other closed-source software.
• I confirm that I have provided the complete configuration files and logs, rather than just providing parts I think are useful out of confidence in my own intelligence.

Start with the SFA remote-profile flow and its autoupdate setting, then reproduce the minimal HTTPS configuration case using the stated 15-minute interval. Compare the profile's last-update time with the HTTP server request log; done means the profile is fetched again and updated within the configured interval.
