Bugs in atcions

Hello good Morning.
I am having problems with the actions (they write to me on the google sheets) and joint list.
The application is quite complex, but it has been working without problems for more than 3 months
I have an application to order.
in which every time a product is requested, he writes me a line with the data in the google sheets sheet.
The funny thing is, it doesn’t happen all the time. otherwise it happens to Some of the users.
Have any of you had similar problems?
