Would you have a chance to share this file with us or provide us an instruction how to create it ourselves?

Yes, of course. Log in with devel-su and use following:
echo “kernel.yama.ptrace_scope = 0” > /etc/sysctl.d/91-opmobiili.conf

10iii here. Added the sysctl conf, rebooted, and it works.
At least until someone from OP picks up on this 
Thank you!

Forgot: in case OP gets their act together and the app starts working without the setting, simply remove the the sysctl file and the phone is reverted back to original state.
I am puzzled how could something like this have passed QC, as this setting is no way sailfish -specific, but generic linux kernel configuration. Only if most android distros have that 0 as default, I can imagine that the app passes QC, or alternatively there is no QC whatsoever for the OP mobiili.

Seems that OP has tighten Android “routines”. And version 70 is out of date , they got 72 in Play. Seems that they have some rules how many active versions on market.
This fix works on Xperia 10 as expected. Thought, because the line isn’t inside pre-formated text -tags, the quotation marks aren’t the basic ones and they are added as is to the created file:
“kernel.yama.ptrace_scope = 0”
So if you are trying to apply this and the fix isn’t working for you, make sure to edit the file and remove the quotation marks:
kernel.yama.ptrace_scope = 0
From now on, Crédit Mutuel (Fr) will stop in few weeks double authentication by sms, and only the bank’s own application will allow this double authentication, which is necessary for all operations, including simply consulting one’s account on a computer! The last time I tried to install the Crédit Mutuel application, it crashed immediately on opening. Have any of you tried to install this application? What was your experience? Without a micro G? With microG?
Thanks a lot!

In my great wisdom, I deleted the app data in attempt to get the app to work before checking the forum for solution. Changing the ptrace_scope allows the app to start to the welcome screen instead of closing at launch, but the app will still close after some seconds, before you can even hope to login for the first time 
For the ptrace_scope a value of “2” might also work, while keeping things somewhat restrictive.

At least for the paypal app both “0” and “2” work around a crash on startup.
