ports dont link after device reboot

I am going to cut straight to the point. I have a CRS326-24S+2Q+ and the QSFP ports stop working when the connected device reboots. I must physically disconnect and reconnect the cables. I have dealt with this for almost a year now and am just fed up. I searched for updates and noticed that RouterOS had a new version on August 19 2020 that seems to have addressed this exact issue,(crs3xx - fixed QSFP+ interface linking after reboot for CRS326-24S+2Q+) but nothing for SwOS. I have tried resetting and re configuring the switch several times with no luck, just in case someone asks.

Also I am using SwOS not RouterOS as I read the docs and it seems to me like RouterOS is slower than SwOS as it has more unnecessary fluff (for me) to it.

Hear is hoping someone can help.

+1 I have this problem too.

I reboot SwOS via webUI and that usually fixes it.

However there are other issues I find with the QSFP ports... erratic to poor performance. It would be good if someone could help as this appears to be firmware related problem.
CRS326-24S+2Q+RM SwOS v2.12

with proper configuration RouterOS do nothing else, just give commands to switch chip, and the data will NOT leave the switch chip.

Badly configured switch will pass packets to CPU instead of handling direction inside chip - and yes, that is slow.
