I switched from CalyxOS to iodéOS, the experience was smooth, I have all the microg options activated, and as far as I can tell they have the same options activated as what I had in CalyxOS, while they were working perfectly overthere, they are not working on iodé (Boursobank claims the application is not coming from play store)
France identité never worked for me.
My banking app failed on iodé 6.x because of google safetynet issue (there are several forum threads about this). Works on iodé 4.x, though.
How recently did you have them working on CalyxOS? It could be that this was a few months back before Google shut down the SafetyNet attestation servers in the recent past?
I do recall working with some others on Boursobank in the past, I see that it may work via web browser, but I can’t find the other discussion on it (it may be on the brax forum, sorry I don’t have time to look back to it over there just now).
Also just checking if your Boursobank install came via Seedvault restore or was it a new install from Aurora on iodé?
CalyxOS up to last week, it was working ootb. I tested installed from SeedVault, and reinstalled from Aurora
OK that is surprising it was working in Calyx but not in iodéOS. Was the calyx install also at Android 15 base, and this is with the same phone?
The best I could find is the reference to making a web app working fine with Boursobank but it is a bit old now (but maybe still true?)
Both apps work for me on a good old Pixel 3 running Iodé 6.8. Hope it lasts.

Yes it was Android 15 based. No the web version does not help 
Note that I installed it on a grapheneos yesterday on a pixel device (another device) both works ootb.
I second the experience.
Boursobank is not working with my Brax Device.
Tried to add to some comments to Some banking apps identify iodeOS as custom ROM (altered OS) (#44) · Issues · ota / issue-tracker · GitLab - but I’m unable to subcribe to the gitlab instance. User-name validation failed so I’m trying here instead.
Note that it really is a PITA if you can’t start the banking app to validate some money transfers.
Would be nice if you could do something about it.
This issue happens forever - using a Brax3 phone here.
Note that on my OnePlus Enchilada / Lineage OS, Boursobank works.

Yes, unfortunately they haven’t opened their gitlab instance to non-team member registration. I think it is just a “lack of capacity issue” to not want to have to manage / moderate the accounts, etc.
I have added a link to this forum discussion to the issue tracker.
France identité works on Pixel under iodéOS with bootloader relocked.
It does not work on brax3 because of hardware-backed key attestation and remote key provisioning, which is not available for that device :

What about BoursoBank? Same issue?
If anyone has instructions on how to get some logs, I’m will to give it a go on my device.
Well there is a bit of a mixed result here, but the brax3 not supporting hardware attestation as Vincent notes means that it is less likely to work on the brax3.
But for broader iodé support it is a bit uncertain, as @Yasuke reports it works for them on a Pixel 3, but @bapt reports they can’t get it to work (assuming on a Pixel as well).
Maybe it is only working for Yasuke since they activated it some time ago, but if they would remove it and attempt to re-activate they would be unable to do so. I doubt they want to test that 
@bapt do you have your bootloader relocked, and what specific device?
yes the bootloader was locked, note I’m sorry but I can’t test anymore as I installed another OS (I needed boursobank to work, and I don’t have my spare device anymore as well.
