cannot complete or cancel swap

Question

I can't believe this issue is still out there. I was looking at the following discussions (from 2 years ago) and I don't know which is the solution they mentioned there, cause is still happening:

I cannot swap two slots in a web app, actually try to do it in 2 webapps, both same problem (same error mentioned in previous discussions I referenced). Those workarounds did'nt work (well, they did solve the blocked status of the swap, but when trying to swap again, same error).

Now I'm thinking is a veeeryyyy big mistake to depend on the slots to swap applications in production, this is going to screw the process.

Last week I managed to swap 2 webapps, but they were simple windows webapps, the ones from today are linux using azure container registry.
